Hello. I would like to ask for a compat for a resource pack Better Leaves: https://www.curseforge.com/minecraft/texture-packs/motschens-better-leaves

I know Ars trees works with this resource pack.

You need to ask them, it is a texture pack aka it overrides existing assets with theirs, doesn't make sense for a mod dev to make it. The other archwoods work because they made textures and models for them.

Thanks. Already did (TeamMidnightDust/BetterLeavesPack#58).
