The role does not use the ksm service at all but uses file based configuration as per SAP note 2777782 v17 (RHEL 8) and 2292690 v37 (RHEL 7).

As per https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/virtualization_tuning_and_optimization_guide/chap-ksm#sect-KSM-The_KSM_service , the ksm service is part of package qemu-kvm. In RHEL 7 and RHEL 8, as per:
$ yum whatprovides /usr/lib/systemd/system/ksm.service
and
$ yum whatprovides /usr/lib/systemd/system/ksmtuned.service
, the ksm and ksmtuned services are contained in package qemu-kvm-common .
None of these packages will be installed when installing RHEL 7 or RHEL 8 as per SAP notes 2002167 or 2772999 on a virtual system.

To be on the safe side, we could just disable services ksm and ksm.tuned in case the corresponding package is installed or these services are available.
