Currently no.
By current defaults, the buildbot system does not build patented stuff anymore, and exfat falls into that category.
As kmods are tightly tied to the kernel version and options, compatibility requires exactly same version.
In theory, somebody might compile a compatible kmod with the release SDK and place it available (like eduperez has done for new mwlwifi versions), but so far nodoby has done that.
Ps.
regarding exfat, detailed explanation can be found in Exfat package for 4.14? (build patented)
