Updating software switch banks to resolve conflicts (NMEA 2000 facing Victron "Devices")

I have a fairly typical Victron Boat environment (Cerbo GX MK2, Smartshunt, Multiplus II, etc). I have installed a NMEA Gateway and it is working great. The issue I am seeing is that there are 3 different NMEA 2000 Devices (all tagged Victron) that are all trying to use Switch Bank 0 (Multiplus, Smartshunt, Lithium). I am using the Yacht Device Can Viewer software and that does allow me to send sentences to a device to change settings. What is the Sentence I need to send to each device - Ideally, I would like the Muliplus to be on bank 3, Smart Shunt on Bank 4 and the Lithium on Bank 5. I want to keep bank 0 open for future growth, bank 1 is a Yacht Device RTI and bank 2 is a Yacht Device CC04.

Given that all 3 devices are using the same switch bank, that will create conflicts and produce indeterminant behavior.

I appreciate the help!

Hi. The below links may be helpful if you havent found them yourself already:

See also below PDF, which says:

"Data instances (Battery Instance, DC Detailed Instance, Switch bank instance, etc.)
These instances are embedded in the different PGN’s. All Victron products support changing these instances through a complex write, PGN 0x1ED00,
Complex Request Group Function Code 5, write fields." (p.s: IMHO the data instance can [nowadays?] just be set via e.g. the Victron Connect app or the Victron Cerbo menu under NMEA2000, also as written in above links, referred to as Data instance)
