Start Nextcloud client on boot prior to user login

Hi, I run Nextcloud on a server which I also use as a logged-in user. This is Ubuntu 22.04 (question is also for Ubuntu 24.04 too). The server runs the Nextcloud server software as well as a Nextcloud client. The Nextcloud client syncs the data from the Nextcloud server to that of my main user on this same machine. My issue and need is that currently, my main user must be logged in to sync its data with the Nextcloud server running on the main machine. My question is:
Is there any way to automatically start the Nextcloud client on this machine on boot BEFORE the user is logged in? Can the Nextcloud client be run for a particular user(s) without having to log those users in? Many Thanks in advance.
