Tl;DR patching is still working for me so I am leaving it at that
In the past several months I've tried a few other monitors, a projectors, a few different video cards, drivers, settings changes, and none of them made any real difference. I did another round of vision therapy (at $3000 out of pocket) hawked by a "BVD Specialist" who promised they could help me and the therapy did nothing but make my bank account lighter
The only thing that has ever really worked long term has been the eye patch, so I am pretty much going to abandon any more avenues of treatment or investigation and just use that. I can work for several hours staring at the screen with the eye patch and suffer practically no effects, and have been doing so for over a year now. I still average about 3 "problem days" a months where the eye patch is less effective, but that is manageable. If the eye patch ever fails I will jump back into the fray, but for now I am accepting this is the fix until I retire and no longer need to worry about it.
I d not feel that any hardware can solve my BVD, as the software (Windows 10) can make the hardware operate in a way that triggers my BVD symptoms. Knocking out my binocular vision with the patch is the only thing that has worked. I do what I can to limit my screen time but I would say I am still averaging 4-6 hours a days with most days pain free or minimal discomfort. This has allowed me to keep my career and earn a living supporting my family. All from a $1.25 paper eye patch (I find the cheaper paper ones hold their shape better and don't hit your eyelashes, which I find annoying)
So if you haven't tried it yet, give it a shot, other than the endless pirate jokes from my kids, it's not that obtrusive a thing to live with, and the benefits certainly outweigh the downsides.
