I have searched for a long time and have not found it. How can I let him not show it without changing the theme?

There is no normal way, if you insist, you can try to set the foreground and background of the NonText group to the same color, for example:

:hi NonText ctermbg=13
 :hi NonText ctermfg=13

But this just makes the wavy line invisible, it is still there.

PS. I know this is ugly. Try other colors yourself XDDDDD
