Is there any way to use the Roundcube (Installed / Updated according to your module) to run with a newer PHP version (Also available up to 7.3 in /opt/rh)?
The reason would be to be able to run the CardDAV plugin, to achieve synchronisation of Addresses with NextClouds CardDAV…
CardDAV 2.0.2 is the oldest I found, it still needs 5.6.18… Nethserver is using 5.4.16 for Roundcube…
