Can I upgrade my iPhone11 pro Max’s ram to 6 gb?

I bought an iPhone 11 Pro Max just one year ago.

it has 4 gb ram

I have seen that the 12 pro Max has 6 gb ram and it has greatly increased/shortened load times for background apps.

my question is can apple support offer/preform a ram upgrade to iPhone 11 Pro Max at a reasonable price?

the iPhone 11 Pro Max is a flagship and cost is so high it is a shame not to have this high ram feature available.

it would be awesome. I could pay and apple would be free to keep the 4gb ram to reuse for lower cost models in the future.
