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 https://nc.mydomain.com and I want to have https://office.mydomain.com (resolve to same IP).

I found this really useful post by David Clinton about the config https://medium.com/@dbclin/administrating-nextcloud-as-a-snap-4eb43ca6d095

But this follow up https://hackernoon.com/managing-ubuntu-snaps-the-stuff-no-one-tells-you-625dfbe4b26c
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.
