Shared Folder not in Sync with external Storage

I have the problem with Shared folders that not in sync with the storage.
tho understand first the setup of my nextcloud:

i have one time LDAP Users (Company Users)
and second free registered Users ( Internal User Accounts)

for the LDAP User exist a SMB External Storage to the windows File Server (Globaly Configured )

in this share the Workers Share folders with the local Users

if now a file is added (Not over nextcloud, only in the network share)
this file is not visible for the local user account until one of the worker access the shared folder
and the index get refreshed.

sudo -u www-data php occ files:scan --path “/admin/files/Daten/”
-> this works but only if i run it for the user that are shared the links.
an --all tooks to long so its nod possible

is there any way to disable this file cache that nextcloud just read whats on disk or any other solution?

Nextcloud version (eg, 20.0.6): 20.0.6
Operating system and version (eg, Ubuntu 20.04): Debian 10.7
PHP version (eg, 7.4): 7.3.19
