Is it safe to add CloudFlare nameservers to a VPS?

I have an **Ubuntu 22.04 VPS** with public IP and I access the VPS with SSH only, I didn't install a GUI like *xrdp* or *VNC*, I intend to add the CloudFlare nameservers to /etc/resolv.conf and maybe this is what it looks like:

nameserver 1.1.1.1
nameserver 127.0.0.53

Is it safe if I do this? Or will I lose my SSH access to this server?
