Can I reinstall Dappnode OS on my Dappnode Extreme without consequences

Because I cannot get any help for days for my issues with Dappnode Extreme machine,
I guess it is only way to completely reinstall the whole system.

Can I do that without consequences? Will i lode my Nodler ID (which i still don’t know what is it used for), if I reinstall it? Or can I find some other problems?
