Maybe kernel with forced backport patches ?
Need disable some media_build backport patches (v6.1_class.patch) in media_build/backports/backports.txt

[pszemus]

That's it! RedHat backported lot of changes to kernel 5.14.0_362 in AlmaLinux 9.3 (iteration #362 !!!), even from kernel 6.1 :-o
By trial and error i came up with the following backports.txt addition:

+[5.14.0]
+delete v6.1_class.patch
+delete v5.18_rc.patch
+delete v5.17_iosys.patch
+delete v5.14_bus_void_return.patch
+
