I am using Linstor with Proxmox. By default, when creating a virtual machine, its replicas are placed on the same node where the VM was created. This leads to an uneven distribution of load and data.
I need Linstor to automatically distribute replicas evenly across the entire cluster, regardless of which node the VM is created on.
How can I configure AutoPlace to achieve this behavior? I would appreciate any advice and example commands for the setup.
Assuming that you have not set the option preferlocal yes in the Proxmox plugin configuration, you should be able to use the x-replicas-on-different argument with configured auxillery properties as described here:

Matt K’s blog post Distributing Volume Replicas for High Availability & Disaster Recovery Using LINSTOR provides more information about this that may be helpful to you here:
this is the default forever, so yes, the user has that (implicitly) set. I changed that some years(?) ago as having access to local/fast storage is what 99% of users want as their default.
