looking for advice on whether it is allowed to use dry lining boxes if in stalling dimmer switches I a stud wall 

 
My favourite DL boxes are Appleby, they never give problems, but some of them are dire.

If you really think you are going to have a problem with your dimmer, TLC sell metal dry lining boxes complete with an intumescent seal in the back.

 
Its allowed, but go for as deep a box as your can to give extra air space around it.
