Setting Default for the samesite attribute of the cookies

Hi there,

I’m very new to Nextcloud. I just installed a small test with version 18.0.2 on Nginx (1.14.1) and CentOS OS. In preparation for the incoming Chrome versions, I wonder if there is a way to set a default for all the cookie to have samesite=None? I tried to search around in the documentation and the configuration examples but didn’t manage to find anything.
