Today the usual zypper dup came along with 7.2.0-1-default.

amdgpu.dcfeaturemask=0x402 into /etc/default/grub for GRUB_CMDLINE_LINUX_DEFAULT 
(no bls grub),
then
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
then reboot
and now the Display-settings show 300Hz for my monitor and after setting this
the monitor display works with 300Hz.

Even with my TESmart HKS401-M24 KVM switch.

Very nice.
Thanks to AMD and the TW gods.
