Talked to Equifax rep, recommended something I haven't heard much about for deletions. Help, thoughts?

So, a little backstory. I have been on the road to rebuilding my credit after being an absolute asshat in my early 20s. Currently I am looking to get rid of 2 big accounts as soon as possible so the upcoming house search and mortgage lender search isn't as tumultuous. They are both from USAA and are in the 7.5 year range for deletion.

I have already reached out to TransUnion and in December they removed the 2 big accounts from my TransUnion report, giving it a nice bump of +18 points. Now, fast forward to now, trying to get them off my Equifax and Experian. For Experian, I reached out and talked to a rep, and for their report they are scheduled to fall off Feb 2021 and Apr 2021. The Experian rep informed me to call back at the end of Jan and the beginning of March to get those 2 deleted a month early from my report.

ok, good so far.

Now, reached out to Equifax, and after a maze of pressing numbers for the automated machine to eventually get tired of me, I was put through to a person. Guys name is George, and nice enough, shout out George at Equifax. He informs me that for the 2 big accounts, they are both set to fall off in April 2021 and to call back March 1st 2021 to get them off as soon as possible is an option. Next he tells me something which has now brought me here. He tells me that its possible to call the actual lender, i.e. USAA, and in short, ask them to remove it early, as in like now. He himself said it was a coin toss but its possible for them to do it being so close within the range. My questions now being, is this true? If so, anybody have any experience with it and which department I should call to discuss it with (not specifically for USAA but any info as to which department in general would help)? There's also some scary questions.. like, if I do call, can they restart the clock? Even know its been 7 plus years now, can they come back after me?( I looked up the laws in my state and its way past the deadline to come after me for it but big corporations got the pull to do whatever) Could calling them and asking to delete work for both Experian and Equifax? Maybe provide information that its off of TransUnion already? Any information would be greatly appreciated and I thank you all in advance. My fico 8 currently sits at a 678 from a 489 last year thanks to this thread, so seriously thanks to everyone out there who gave advice!
