You can't. You will have to update your 32 bit applications to the latest version which should by now be 64 bit version, or find alternatives if a 64 bit version is not available. Software developers were told nearly three years ago that 64 bit only Macintosh operating systems were coming.


In their support document 32-bit app compatibility with macOS High Sierra 10.13.4 and later Apple advises:

"Starting with macOS Catalina, 32-bit apps are no longer compatible with macOS."

Whether or not this may help to 'upgrade those 32-bit apps and drivers' after the fact

since change-over was before Catalina 10.15.7 hit the pan, this free resource is helpful.
