No. If your batt is 80Ah, code it to 80Ah. Stock I believe is default to 90Ah.
That's why buying the 90Ah batt is so much simpler.

I bought 90Ah batt, then coded it to 80Ah, then I had hard time going back to 90Ah. It was PITA till I figured it out. I could do it easily after.

It's been a while but I created a NCS FSW_PSW.MAN file from TRC file I think(over a year ago now). And replace the 80Ah value to 90Ah. Flash the file to DME.
There's a DIY - "Aftermarket battery registration DIY.PDF".
