It is theoretically possible to carry out adult activities without taking your clothes off - witness the fumblings outside (and sometimes inside!) pubs and clubs. This behaviour usually only raises a laugh.
However, the adult industry relies upon paying spectators and these normally require that they see some or all of the performers bodies in an unclothed state. They want to see what is nappening. So, a scene might begin with the performes having their clothes on, but, it leads to the clothes being discarded in some way.
The only exception I am aware of is CFNM (clothed female, nude male) for which there is very little demand. I cannot see any company I know paying clothed actors on any regular basis.
So, there may be a very limited chance of getting clothed adult work, but, don't count on being paid to do it.
The profile specification can only come from someone who does not know what adult work means.
