Use the following to try the 5.10.0-rc1 kernel:

sudo zypper ar http://download.opensuse.org/repositories/Kernel:/HEAD/standard \ 
KOTD
sudo zypper dist-upgrade --allow-vendor-change --from kernel-repo
sudo zypper install kernel-default-5.10.rc1-3.1.g91029f0.x86_64

One warning: This kernel will not work with VirtualBox. There is one 
incompatibility with 5.10 that I still have to solve.
