fvwm implementing theme

So I am starting to learn on how to configure fvwm and play with themes to make it easier to use.
Please note, I am working on remote machine and don’t have admin/root rights.
Everytime I add something in $HOME/.fvwm* files I have to start a new fvwm session.

Is there anyway I can implement the settings in live fvwm session?

Added later: I am working on a unix machine with FVWM interface.

Using fvwmcommand to test what you later put in .fvwmrc ?
Using the “restart fvwm” button in your root menu (if you have any) after editing .fvwmrc ?
