Fannie Mae on LLCs & Due-on-Sale

I've been reading about transferring a personal mortgage to an LLC and thought it would be a good idea for my personal investing journey - though I don't have any properties yet. One thing that I've seen come up is that if you transfer the mortgage to an LLC the bank can call due-on-sale (though they rarely do) and then you could be facing foreclosure. Not ideal.

I was browsing on another real estate investing forum and came across this article: https://www.fanniemae.com/content/guide/servicing/d1/4.1/02.html

5 Black dots down, 5 white dots down, it mentions that LLCs should (would?) be excluded from due-on-sale regulations.

Do any of you more experienced investors have additional information? Have you dealt with this recently?
