Please wait with it. Do not update yet. A small forum search would have shown you that there is an issue with the latest G07 and kernel.
When the issue is fixed:
Changing from G06 to G07 is as simple as deleting G06 and installing the G07 meta package. G06 can be simply uninstalled by searching for the installed packages and deleting/uninstalling them.
A one liner for uninstalling:
rpm -e $(rpm -qa | grep -e ^nvidia -e ^libnvidia | grep -v container)
A one liner for installing:
zypper in nvidia-open-driver-G07-signed-kmp-meta
