No. YaST reads whatever is defined in control file which points to
https://download.opensuse.org/YaST/Repos/openSUSE_Leap_15.2_Servers.xml with
content:

<productDefines xmlns:config="http://www.suse.com/1.0/configns"
xmlns="http://www.suse.com/1.0/yast2ns">
<servers config:type="list">
<item>
<link>https://download.opensuse.org/YaST/Repos/_openSUSE_Leap_15.2_Default.xml</link>
<installation_repo config:type="boolean">true</installation_repo>
<official config:type="boolean">true</official>
</item>
</servers>
</productDefines>

No community repo. I do not know who maintains this file
(openSUSE_Leap_15.2_Servers.xml)
