How (if possible) can I connect to MC realm using Tekkit mods

[slovesk]

I am new to MC and have just purchased a realm from the official site. I was recommended technic launchers for modification ability, but realized, at least in TekkitLite that there is no place for entry of my realm information. (Single Player, Multi-Player, Server).Is it possible for me to enter my realm through a technic launcher, or do I have to use MC's official one?

Realms doesn't support mods at all, you need to rent a proper server host for multiplayer modded server

As disconsented said, realms is only for vanilla minecraft.
