No, encryption isn't going to help, because they can still block on IPs. Encryption plus eSNI helps, and if, for example, Yandex.Cloud sets up a big "shared host," I fully expect that to get the Kharkiv treatment, like Roskomnadzor tried a few years ago with Telegram.
Tor operators can see the IP, they can see the DNS, and their operation has the effect of unblocking RT.
