Shrink Disk Space for Virtual MacOS Tahoe

Hi everyone. I also opened a support ticket, but I haven't received any support in 10 days.

I need to shrink my MacOS Tahoe virtual machine, which has a minimum size of 128GB. I've tried everything without success.
Has anyone succeeded?

I need it to test three or four identical virtual machines, which, with a traditional size of about 40GB, fit inside the HD; with the current size of 128GB, however, it's impossible.

Is there any way anyone can share a ready-made VM in .macvm format with the reduced size?
