If you want to upgrade to something earlier than Big Sur (Mojave?), this might help—it has download links to older versions of OSX:

Why not just update the operating system?

For those asking why the OP needs to upgrade...InDesign 2021 has been out for a year and may need to be on the most up to date version for any collaboration.

Ask yourself once in a while: do I really need the updated version? What's in it that compensates for the trouble you usually get with unthoroughly tested software, as software usually is?

It's still a natural thing that new versions bring new features, but also new problems.

None, if you stay at High Sierra. CC2020 is your max if your laptop is not able to upgrade to at least Mojave.

Is there a particular reason you need to update? CC2020 is still very much a viable version.
