Can I install an older version of iTunes?

I'd like to delete the new Music, Podcasts and AppleTV apps from my MacBook and install the older version of iTunes 12.8.2. Is it possible to do so on macOS Catalina?

I tried to delete the apps from Applications, but it wouldn't let me.

Also, it doesn't let me to instal the older version of iTunes.

When deleting the apps I followed these instructions: https://blog.pcrisk.com/mac/12506-how-to-install-older-version-of-itunes

I noticed that the author gives three versions of the same command:

1. sudo rm -rf iTunes.app
2. sudo rm -rf /iTunes/app/
3. sudo rm -rf /itunes.app/

Maybe there's a mistake somewhere?

I tried to write Music and Podcasts instead of iTunes but it was unsuccessful. I couldn't delete it.
