2 Hyper-V VM environment and DB is 10Gb, anything I can clear out?

Have a Case #05479456, tech advised posting in here as the other commands he sent over did not reduce it with any substance.
With SQL Express there is that pesky 10Gb limit to the database. We have clients with many more VMs and their Veeam SQL databases are a fraction of this one.
Did a query that listed the sizes of tables and there are quite a few more than 1 GB and wondering if I can clear out some old data so we can continue to use SQL express, as the client will not opt for a full SQL license.
Here is the table listing and sizes if anyone knows which I can clean up?

Another shot by number of rows.

Most of the data looks like its taken up by restore points, which looks like it would be important to keep. However, have you tried to determine how long you're keeping session data for and make sure it is as low as reasonably possible?

The other thing you could do is contact support for any advice they might have.

I have set the retention to 7 days but did not make a difference
And I have reached out to support and they directed me here,
