Upgraded to the 4K HDHOMERUN, how do I get rid of the old one?

I was just talking with support and downloaded the new beta and my IPAD still has no sound on astc 3.0 channels but i found this

AC4 maynot be support on older idevices.even if they are on ios 14 basicly any idevice before 2018.

i sent this to support.

And that the beta on my Iphone 11 works with audio

Why get rid of the old one? Just move the new one to higher priority, and keep the old one active to have extra tuners.
