No. You'd have to reconfigure libvirtd to work in plaintext
vdsm-tool congfigure --force
and also set you Engine to work in plaintext (unfortunately, I don't
recall how's that done. surely Yaniv does)

It's safe in the sense that I have not heard of a single failure to
reconnected to already-running VMs in years. However, this is still not
recommended for production environment, and particularly not if one of
the VMs is defined as highly-available. This can end up with your host
being fenced and all your VMs dead.
