Hi everyone, please, can you limit the "Create VM" process somewhere so that
setting up quota does not load the server so much, especially storage when duplicating the
template disk?

I assume you refer to the process (qemu-img) that clones the disks, right?
Did you consider changing the storage allocation to "thin" instead of
"clone"?

Hi, no, we don't use bit cloning via "clone" function, but we use templates
as a raw format template.
When creating a VM through this template, the server load will increase a lot.
We want to minimize this sharp increase during the establishment. We are willing to wait
longer to set up the server.

Try what Arik suggested:
Open VM > Resource Allocation tab
Set "Storage Allocation" to "Thin"
This will create create an empty qcow2 image using the template disk
as a backing file.
No data will be copied when creating the VM.
But note that this creates a dependency on the template. You will not
be able to move
the disk to another storage domain without copying the template to the
other storage
domain. This also creates a single point of failure - if the template
become corrupted all
the vm on top of it will break.
