A good ppf installer might even be able to cut out a patch of the ppf, polish out the damage and then patch back the ppf. Not ideal, but your roof is black so it won't be very obvious (if done correctly).
but I did find this.

For my touch ups, you can’t see them at 5 feet away. The ultra clear epoxy resin will make the “white” disappear, will dry to a gloss finish, and makes the carbon look black again. it’s not perfect if you run your fingers across it, because it still isn’t perfectly flat, just like using touch up paint. If you really wanted to get it flat you would need to block it with a small block and sand paper, maybe go over it a second coat to fill in any remaining low spot, then polish.
My .02, I would just dab the epoxy in and touch it up best you can. You will get more eventually. Removing the whole roof of PPF and blocking, polishing, or re clearing is a lot of work. If you get a couple years down the road and have several touch ups that you want to smooth out, then you will be half way there and can just re clear the roof.
FYI, thats more than clear thats chipped away. Thats part of the resin as well when you’ve chipped down do the composite. Clear isn’t that thick.
Fwiw, on my example it was the edge of the M Performance carbon front lip. It got bit by a driveway transition that caught me by surprise. I had 4 or 5 rock size chips, had to cut the PPF off around that area, and did exactly as I’m suggesting. I masked it off as a precaution, but did not touch up to the edge of the mask. Just brushed it, dabbed it in carefully. I’ve had people look at it from 3 feet and cant see it. you have to feel it to know its there.

If you want to fully repair it, remove ppf, apply a few drops of 2k clear making a nib, give a few days for cure, cut the nib with 2000 grit and hard sanding block, polish and apply new ppf.
Don’t use resin, it’s useless for this small void. Your clear is damaged, not the resin.

As others had stated, the stone went through PPF and through clear coat layers, maybe digging into the epoxy on top of the CF. It's a little hard to judge from the picture how deep it went. But if it compromised epoxy / CF layer, it should be repaired to avoid spreading.
overcoil wroteIf the chip went into the epoxy/CF layer, you do NOT want to leave it as-is.personally I would not fix it would not bother me.
Same as with a chip that went through paint and exposed bare metal on a roof, if left unmitigated, the damage will spread and only add up to a larger repair bill later.
If epoxy layer is penetrated, you will need to clean and fill in the area with new clear epoxy. Then a bit of clear coat paint on top, level and polish. New PPF on top is optional.
Repair maybe visible from a few feet away, but structurally it will be as good as new.
If you are are DIY-er and have worked with epoxy before - you can do it yourself. PPF needs to come off first.
Otherwise, pay someone competent to do it for you.

Carbontrims What specific 2k clear would you recommend?
MALAKA5 wroteAny clear coat from a trusted manufacturer should be good. It’s difficult to recommend specific brands because availability varies from country to country.
You likely won’t regret choosing a clear coat whose TDS recommends a relatively high percentage of reducer, as this allows you to adjust the viscosity more easily, which is especially useful for spot repairs.
For example, you could check out Roberlo 150 HS or Dynacoat 6000.
