Non-load bearing brick wall, stripped back. Wet-plaster, dry-line or replace with stud

I'm stripping my bathroom out, when the anaglypta came off the wall chunks of the original 1930s render/plaster about 2ft across came with it. The brickwork behind is a bit haphazard, and I think was being held together by the plaster, because some of the mortar isn't great. Some of the plaster was a couple of mm thick whilst some was nearly a couple of inches.
My original plan was to just fix tile-backer board to the brickwork (either screwed or dot and dab), but seeing what a state it's in I'm wondering if that's the best option, if I should get it re-rendered to shore up the wall, or just take out the bricks and replace with a stud wall instead.
Are you a tradesperson and able to answer this question?
The quickest and cheapest would be to dot and dab with plasterboard making sure you sbr the old brickwork stopping and damp migrating through your adhesive rendering would be stronger but more expensive taking old wall and putting up a partion would be best job but cost the most

Any off the above will do.I personally would give a coat of boarding coat to level wall and then stick tile backer on top
If the plaster is wet there is potentially damp which means finding the source of the leak fixing that then drying out the bricks then treating them with an inhibitor then sand and cement backing to bring the wall back to level then skim over the whole lot that's the proper way to do it so you never have this issue again if there is damp do not dot and dab as the damp will just damage the plasterboard adhesive and will come away from the wall along with anything you out over the top of it screwing tilebacker or stud walling are both sound options but again if there is damp it's just gonna destroy those over time as well
If you can find source of damp, if You dot and dab make sure you use moisture resistant board, or float in sand and cement using a waterproofer and skim as it’s in a bathroom.
With the old render disturbed now, I would recommend to take the brick wall down and replace with stud wall. You will have an idea of where damp is originating from as well. It might be a bit more expensive but you have that piece of mind.
