Hi, unfortunately, as far as I know the standard doesn't have this functionality.
But starting from BC23, Microsoft has released the following feature, which will automatically update when the version is updated. I think this can solve your problem.
Business Central 2023 wave 2 (BC23): Automatically update AppSource apps with minor updates (Apps Update Cadence)
I may be pointing out the obvious, but user who has access to admin center could update extension from the following screen. Or you could ask you ISV to notify you when major updates are available and I think they will be happy to help.
