Any solution for bypassing font checks?

[Contours]

I have a situation where I'm bringing a couple hundred XAR files from an older PC. Many of the font uses were experimental ... installed fonts ... Google fonts ... downloaded fonts.

Almost every file I open complains about missing fonts and offers to download them. I don't care about the missing fonts ... and I expect substitutions. I don't even mind having such things flagged. But the dialogs are downright annoying ... and tedious to dismiss. They are ruining my day(s).

XaReg2 has a few features for turning off checks. But I can't find anything about fonts.

Does anyone know of any way to bypass these checks upon loading a file? Even a regedit would be fine.

Thanks in advance for any advice.
