I would like to use my iMac Desktop 2017 (macOS Big Sur Version 11.2.1) as a screen only for my new MacBook Air M1 2020 (macOS Big Sur Version 11.2.3).
Thank you!
You can't. Apple stopped supporting that feature many years ago and with a M1 Mac and Big Sur you will be lucky to get it to work, even if you had a supported iMac (which you don't).
Use your iMac as a display with Target Display Mode - Apple Support - https://support.apple.com/HT204592 - iMacs late 2009-Mid 2014. This document is "archived" which means this feature is no longer supported by Apple for recents Macs and operating system versions.
This could only be done with a very few and very specific older iMacs and support was very limited. Read this topic for a 2021 perspective on this: https://discussions.apple.com/thread/252271436?answerId=254300142022#254300142022

You have only 2 options:
may suffice for your use.
The new Mac is running Big Sur which very likely does not support this feature (see the review links I posted). You essentially need a complete setup that dates from several years ago in all aspects.
Thank you so much for the response! I also have the following computer I can use as a display. Could this work? If so, can you let me know what cords I'd need to connect?
Thank you!
