Can I run Collabora or onlyoffice on the same ubuntu 19.04 with nextcloud installed by snap?

So my issue as far as I can tell is that apache & its configuration is hidden away in the snap install, and I will need to add a virtual host
Currently my nextcloud works fine and I want to have (resolve to same IP).

I found this really useful post by David Clinton about the config

But this follow up
Suggests that the apache config is read only inside the snap… So is it not possible to do?

I’m not worried about performance as its only for 2-3 users.
