2019 i3 display upgrade from 6.5 to 10.25

[Old dog]

Hi Guys,
I have a 2019 i3 Rex, Went to the dealer to get a price on a upgrade from  the 6.5" display to the 10.25 display, They said they cant, because they didn't have a part number.
Anyone know the part number for the10.25 display and where I can order the from?
[b]UPDATE:[/b] fund & installed a 10.25 display Product Date of 07/10/2021, Part #BM6842991 03.
Coded as per the seller on E-Bay & as per BimmerCode [b]NOTE:[/b] BOTH CODES DID NOT WORK (so I don't what to post them hear).
From what I can find these head units coded to vehicles pacific [b]VIN[/b] number [b](Anyone know just how this is done)[/b]?

I have heard different things, like having to change modules and not possible at all.
Anyone know the hardware and software to do this??
Thank you in advance.
