I do not think there were actually changes in the kernel; see your kernel
config instead. On Mint, this should be in /boot/config-* files
For example my Ubuntu Focal is showing most of vfio drivers are built into
kernel rather than as modules:
bronek@lipowa /lib/modules/5.4.0-33-generic % find
A search of the modules for 5.4 vs 5.3 shows several vfio modules missing.
I guess there is some big change to 5.4 that I need to know about.
$ find /lib/modules/5.4.43-050443-generic/ | grep vfio
/lib/modules/5.4.43-050443-generic/kernel/drivers/vfio
/lib/modules/5.4.43-050443-generic/kernel/dri
