Will the alternator charge house batteries while driving?

[FunCamp]

2004 Monaco knight. I recently had to purchase new house batteries for my 2004 Monaco night. I purchased a lithium 460ah battery and I am looking to make sure that the alternator won’t charge the house battery while driving and only charge the chassis batteries. I do know from my research that I’ve done that the alternator has an isolator relay delay switch, which supposedly is bi directional and will charge house and chassis batteries while driving. This is a problem as the alternator can’t support the draw from the lithium batteries. My question is, is there a way to disable/unplug this isolator relay delay switch to keep this from happening and only charge the chassis batteries? Also, is there a way to test the relay? Does anyone know the parameters in which it kicks on and kicks off? The manual doesn’t have any information about what the relay delay switch does or the parameters. I appreciate any all information anyone is able to provide. Thank you.

It's not rocket science, I'd just remove the big connecting cables in the third picture. Or you could remove the small wires from that solenoid if you wanted to preserve the function for possible future use.
