Sharepoint 2016: Remove https on central administration page

[vecon]

I ran the command to set securelayer for SP Central Administration page with port 443.
I also want to set https for the Web Application using port 443, but when I tried to use that port for the web application, it has a conflict.  I think i know why because there is only 1 IP on the server and all the ports are set to use "all unassigned".

What should I do so I can have both site to use port 443 if not assigning another IP to one of the sites?
Is it how it work with sharepoint, every additional web application I create will have its own IP? I don't know how people usually do with Web Applications and Central Administration page using port 443 and https

For right now, my priority is to give https to the web application but I don't know how to remove the https from the Central Administration site as it was set by running the command.

Please advise.

I kindda resolve the problem with Central Administration page (thanks to Grace Wang):

Navigate to Central Administration site->Application Management->Configure alternate access mappings, click “Edit Public URLs”, select relevant web application, make sure the default zone is
http://adfs-sharepoint:8080
.

In the IIS, select “SharePoint Central Administration v4” and click “Bindings…” in the left Actions panel, add a binding with the http type and 8080 port, then run reset IIS via Start->Run->type “iisreset”->OK.


However, the https and port 443 is still showing up on the IIS for Sharepoint Central Administration v4 site

Any Web Application I added in, i cannot browse to it anymore. I kept geting 401 error
