Problem you are having

Currently Baikal hardcodes some plugins:

Baikal/Core/Frameworks/Baikal/Core/Server.php

Lines 155 to 160 in 49b610c

	$this->server = new \Sabre\DAV\Server($nodes);
	$this->server->setBaseUri($this->baseUri);
	$this->server->addPlugin(new \Sabre\DAV\Auth\Plugin($authBackend, $this->authRealm));
	$this->server->addPlugin(new \Sabre\DAVACL\Plugin());
	$this->server->addPlugin(new \Sabre\DAV\Browser\Plugin());

The only plugins that can be disabled are ones related to disabling CalDAV/CardDAV. Since I don't trust users to not break things by accident, I would like to also be able to disable the \Sabre\DAV\Browser\Plugin plugin.

Suggested solution

Introduce new dav_browser_enabled config option that defaults to true in baikal.yaml. Then such option can be controlled in the same way as CalDAV/CardDAV flag.

---

Since Browser "hijacks" *DAV URLs, the browser cannot easily be easily cut-out on the edge with reverse proxy (I tried even as far as matching Content-Type on response ;)). sabre/dev also doesn't have a clean remove_plugin() method or any hook to do so. So the only way now is to apply a manual patch, which is less than ideal.
