One common bin

[adam23450]

Is it possible to make one common trash for all pools on one of the disks? If so, how can I do it?

ZFS has no trash, this is handled by the client OS which mounts the shares. So I guess the answer is "no".

But the SMB share already has.
Whether it is possible to do with the SMB share so that the garbage ends up in a given share - one for all

To the client, each share is a distinct drive.
If you know a way to plug two HDDs in Windows, format them as independent file systems but have Windows manage a common trash for, say, drives D: and E:, you can do what you want. If not, you cannot do it. ZFS or TrueNAS has no relevance here.
