iOS 14.7.1 Mail App font substitutions

Is there a way to change the font substitution used for Comic Sans in the iOS mail app? Since there is no iOS Comic Sans font an easy way to tell iOS/mail app to use what I want instead of just making what I consider a very poor choice. I get emails from a group and one of the users has decided to use Microsoft's "Comic Sans" as his default email font. This is no problem on my Mac but on my iPhone and iPad the font gets changed to a script font that is nearly unreadable especially on my iPhone unless you enlarge it considerably. It's almost as hard to read as something typed in ALL CAPS...

 I would prefer something like a Roman or Helvetica font.

Thanks,

David
