Hi Chris,
The setting is controlled through the following on the config:
Compliance Management -->SPL-->Control settings for SPL
Within the same, select SPLUS and look for Scope of check. Under the same, "Check logic of Docs" would be selected as "New Check of Changed Addresses" in the standard, you can change it.
The change is not recommended as there is always a possibility that somebody from the ordering team or logistics team can change the address and it ends up at unwanted parties in the absence of screening of updated addresses.
Hope it helps!
