You probably have to inquire with the vendor support who supplied the kernel, but checking on a UEK kernel I have of that major version I see this (mine is el7 not el8, but I suspect the both UEK kernels are basically identical). grep -i clone /boot/config-5.4.17-2102.203.6.el7uek.x86_64 # CONFIG_DM_CLONE is not set So it was not configured/compiled into my kernel and likely not yours. And dm-clone appears to have initially been added in 5.4 from what I can tell so I have zero clue how stable/functional it was in that version even if it was enabled.
