Building AUR linux-ck with modprobed-db in a clean chroot

Trying to build linux-ck using this edited PKGBUILD:

selected clang, subarch and included modprobed.db which I put in the main folder

$ git diff -U0

And modprobed.db file

The kernel builds without errors almost everything is fine, except one thing. When I run makepkg -rs it builds the package linux-ck-6.8.1-1-x86_64.pkg.tar.zst as it should - about 15 mb in size and compiles for a couple hours. But when I run pkgctl build with the same PKGBUILD and modprobed.db files -  the same package is generated, but 132 mb in size and the compilation procedure takes twice as long.

PKGBUILD has a command that saves config.last files and I have already compared them, after makepkg and pkgctl, they are identical.
/etc/makepkg.conf and /usr/share/devtools/makepkg.conf.d/x86_64.conf   have not been modified.

It seems that when you build in a clean chroot it compiles with all available kernel modules, despite the modprobed reduction procedure

Any thought or advises?
