Remove “class=….” entry from images in posts?

I’m using the Classic Editor and the 20/16 VCReady theme.

Is there any way to remove the

class=”align….. size-…. wp-image-…”

entry from images inside posts?

Does it serve any useful purpose? On my site, it doesn’t appear to do that. It also appears at either the start or the end of the img statement, but is not consistent.
