You should be able to change it from the GUI: Edit -> Show Advanced
Options -> System -> General -> Provide Custom serial number policy ->
Custom serial number.

You can also change it with the API, for example with the Python SDK:

---8<---
#!/usr/bin/python

from ovirtsdk.api import API
from ovirtsdk.xml import params

# Connect to the server:
api = API(
    url="https://rhevm36.example.com/ovirt-engine/api",
    username="admin at internal",
    password="...",
    ca_file="/etc/pki/ovirt-engine/ca.pem",
    debug=True
)

# Find the VM:
vm = api.vms.get(name="myvm")

# Set a custom serial number:
vm.set_serial_number(
    params.SerialNumber(
        policy="custom",
        value="myserialnumber",
    )
)
vm.update()

# Disconnect:
api.disconnect()
