Are libvirtd-tcp.socket and libvirtd-tls.socket necessary for kvm?

As the title says, I am curious if these are necessary because after enabling libvirtd and rebooting, when I check status libvirtd, I see that these 2 processes are not running, and the rest of libvirt is running. Kvm virtual machines work fine, but is tls and tcp not functional for them? Should I enable them both, or leave as is? Thanks.

Thank you for your detailed reply. I don’t need remote access to libvirt (outside the computer it is running on), so I will leave them off.
