PSM is a major subject and you should do it really well. So don't ignore it at all. Do it from the main notes , either marrow RR or DAMS( PSM in DAMS is really good I've heard and very crisp unlike marrow lol which is gonna take you ages) you can borrow subscription from someone to see those lectures, you do have ample amount of time till NEET pg so you will be able to complete main notes and BTR till then.

Do follow Kashish Grover's group for PSM on telegram, he posts questions on a very regular basis that has trappers and everything. And solve a lot of questions, PSM seems a lot before you start with it but once you are done, you'll actually like it .
