I don't see the screenshot in your post for some reason ?
As for disabling swap, I think there is a Terminal command, though I have to say - you shouldn't do it. macOS is a very smart, Unix-based OS that does these things well. Computers and computer OS-es have changed a lot in years, and while swap was once something to fall back on when users run out of memory, these days (especially with SSDs) it's more a method of making your computer faster, not slower.
I honestly don't know why your computer has annoying delays - but I really doubt it has to do with swap. It could be a different issue entirely (have you tried a clean OS reinstall?). I never heard of a computer slowing down due to swap, but I have heard and seen computers slowing down from background processes, memory leaks, app freezes, etc.
Again - please don't take my word for it. If you think this is the cause, you do what you think is best. If you really want, you can try disabling swap and report if the stutters have disappeared. Again, do this at your own risk, I think this is best left to macOS to manage.
I found this article about it (I haven't tried it and I'm not going to - but if you want to have a go at it, here you are):
