Mac OS High Sierra USB Boot

I am currently using my 2020 iMac running Big Sur and want to repair my 2007 iMac running High Sierra.

Can I create a USB Bootable drive from my New iMac to aid me in fixing my Old iMac?

You can't download High Sierra to a 2020 iMac. You need access to a Mac old enough that could run High Sierra in order to download a copy.
