The python3-tkinter package is a sub package of the python3 source package, which includes platform-python. They are versioned together, so you can’t upgrade one without needing the updates for the other. Since python3-tkinter is in AppStream, maybe you don’t have that enabled? You need the 8Stream repo, not the one for base 8. See the spec file to see it is a sub package: https://git.centos.org/rpms/python3/blob/c8s/f/SPECS/python3.spec#_830 — Jonathan Billings
