I used the EPICFIGRIG addon to rig a LEGO Mandalorian and now I don’t know how to hid the controls and unhide the bones for exporting to UE 5.6
Why do you need to hide or unhide bones before exporting? 
but if you want to, it is done in the data menu (the running man icon) by showing all and un-soloing all bone collections. For the exporting process, does this tutorial help you?
