Legally you can mount it however you want as long as it is part of the additional hardware list or not restricted.
You can't use tape because you can only use electrical tape as an insulator.

I have seen Velcro used. It is very simple and easy to replace a victor then.

I think the most common is to use bolts through the mounting holes. 6-32 screws fit very nicely in the holes for the victors. We normally just tap what we are screwing into (almost always 1/4 inch lexan) Works very nicely and no need to deal with nuts when you are in a rush to replace a victor.
