Need Help How to Install Collabora Online without Dockers? on OS: Linux OS (+CentOs 7 - 64Bit)

I have install NextCloud 11 on my server and its working fine. Now I had reqested my hosting provider to please install Collabora online on the server but they have refused to install because of following reason:

However, we would discourage you from using it as it’s been reported that it causes serious conflicts with Cpanel.

This includes conflicts with your Iptables and webserver due to how WHM and Cpanel behave. Because of this, I’m going to recommend we no longer continue with this request in order to prevent damage to the servers system.

can anyone please helpme in this?

i need to know the result with you because i have same server can you tell me ?
