Hide all users for normal account in instance

Nextcloud version (eg, 20.0.5): 20.0.6
Operating system and version (eg, Ubuntu 20.04): docker-alpine-fpm
Apache or nginx version (eg, Apache 2.4.25): docker-alpine-fpm
PHP version (eg, 7.4): docker-alipne-fpm

There is any option to hide users so taht no one can see each other on same instance ?

Thanks in advnaced,

ok… I just added user without groups, and then selected:
Restrict users to only share with users in their groups

and it’s works :wink:
