You surely want to figure out why the underfull (badness 10000) warnings are happening. My guess is that you are ending lines inappropriately with \\. That's not the way to end a paragraph. And the fact that so many paragraphs have multiple underfull lines makes me think you are using something like \sloppy; that should be a last resort. We could make better guesses if we could see some of the affected material, and even better, a small compilable example showing the input for some of these problem areas.

Yes. At first, I would like to suppress them all. Is it possible? My example is too big to present . I looked for something like \ WarningFilter {latex} {Underfull \ hbox} but it doesn't work. Then if it works, I can cut my example out and show it. But I'm afraid I did it on purpose and they should stay, and that's not the end of the paragraph but equations which I have to correct but on this moment I need to suppres warnings because they disrtact me.

you can (but should not) set \hbadness=10000 and \hfuzz=\maxdimen but this is a duplicate, I'll find an answer
