Vehicle off key out of ignition..first minute or so well over an amp as body control modules calm down. The reading pictured after half hour . Hope this helps others.

40mA is what my 2016 measured also.

Did you have 'approach lights' on? Myself, I've got the BCM set for "Dark Mode" and interior lights on 'Off' , not 'Auto'. Also permanently wired in "battery maintainer" solar panel [doesn't do anything when car is in shade but helps to reduce parasitic draw often enough].

You have replaced all of the suspect mechanical components. You may have a problem components related to ABS, traction control or hill assist. You need to a scan tool (Forscan or other professional scan tool) to check for codes to see if the ABS or other systems are being activated. A message should appear in the center message center if these functions are activated. But there are valves in the Hydraulic Control Unit (HCU) that control the flow of brake fluid to each wheel and maybe one of them are faulty or getting a bad signal from the ABS control unit.
