In CentOS 8, GRUB2 uses 'blscfg' to store bootloader-independent boot
entries in /boot/loader/entries (by default). grub2-mkconfig
generates an initial configuration but grubby modifies the individual
bootloader spec files in the entries directory. After It's updated
the kernel arguments, it overrides the kernelopts in...

Don?t use grub2-mkconfig, it is really only for initial grub configuration. It has a problematic past in CentOS 7 too. Disabling blscfg is possible but it isn?t the default setup and not the recommended way of updating kernel entries.
