You might need to postpone it forever. At least that is what ONE service person said, but we all know they aren't always right about things. I was told to submit a support ticket. I did that in my online account and the next morning I got a reply from them that they removed 2019.40.2.1 from my car and sure enough it was gone. I'm waiting for a more significant future update. I wish there were a "I don't want it" button for software that is optional to install.
