Can someone answer if I can delete the old DNS entries?

Have been running Teams only mode since March 2020.

We have a few users with the PSTN from Microsoft as Add-On. One license is for Polycom Trio (voice only) running the Teams Client app in a Conference Room.

We use a lot of the Microsoft Conferencing Add-on as well.

I cannot determine from the MS docs if we still need the old DNS entries from running Skype for Business Online.  We never had On-Prem.

Can I delete these that MS is still listing in the Org Setup wizard of the Office Admin Portal
