How to disable UFW on Ubuntu if I can't connect via ssh?

Question

SSH

Good afternoon. I'm just learning, and I apologize in advance for possibly stupid questions.
There is a VPS with Ubuntu 18.04 on the cluster under Proxmox, there was access via ssh, but I messed up, turned on ufw and did not add the necessary rule for connecting, now the server rejects all connection attempts.
Can I connect to the server in some other way to disable ufw? There is physical access to the cluster.

Answer 1

Solved the problem. The question was really stupid.
I went to proxmox, and there I launched the console of this server.
