I am unsure how to remove the oil screen for inspection since this is the first time dealing with screens. Always had filters. Debating on moving to remote oil filter adaptor. I have been told that the hex but is vernatherm. Any help is appreciated

Awesome. I was looking for this yesterday but couldn’t find. I was tired with other stuff anyway. Can you please share that doc if possible. Also do I have to remove hex nut 21 to make that screen loose?
No! And that is not a Hex Nut - that is your Vernatherm.
Got it, which means the 21 removal is not needed to take the screen out?
Correct- the screen s held in there by friction right now. Reaching in with two fingers and twisting usually breaks it loose.

Are we going to have a war about whether changing to a filter affects the recommended (and real world appropriate) oil change interval? Personally, I don't believe it does. Oil rapidly loses lubricity as the molecules shear, from heat, and the acidity levels change not to mention things like lead in suspension. Filters don't have any effect on these.
no, Lycoming: oil screen 25 hours, oil filter: 50 hours. If you don't want to follow the manufacturer recommendations that is on you.
Make sure you have the housing and gasket oriented as shown on figure 19.
Before oil filters became popular on airplanes there were millions of hours flown with 50 hour oil changes. Many of the part 134 1/2 operators probably did 100 hours between changes. I do 25 hour changes but if I do a 30 hour trip I don't worry about it.

that's basically the camp I'm in, I'd rather do it early than late. I haven't actually seen a statement from lycoming that says "if you install this stc from some other company our oil change recommendation changes". maybe there is such and I haven't seen it. Personally I'm thinking back many years to o-235 not 320 or 360. many engine specific reasons such as tolerances, metallurgy and so on why they would be different between engines that appear similar.
