RKE2 and Docker

I have a GPU node that already has Docker installed and configured. However, I know want to add this node to a cluster that provisioned using RKE2. I know that RKE2 has it’s own containerd runtime installed (so Docker is NOT necessary). Am I required to remove Docker first? Or can I just leave it alone. (In truth, I would prefer to just leave it there.) Can they both coexist on the same server? Any information would be extremely helpful.

My first four RKE2 clusters were using an older image I had that included Docker CE 19 on CentOS 7. No trouble with RKE2, though I think it confused Prisma Cloud when I installed it a bit that it was there but unused. So probably fine.
