Nvidia update wants to install i386 packages 20.04

[jejeman]

I've received update for Nvidia properity driver 450 (440->450), and it wants to install i386 packages, also for X11 packages as well. Looks to me the whole i386 stack is going to be installed.
Kernel update is also arrived.

I don't have any i386 packages installed on my system. I don't understand why it wants to install i386 packages, along amd64. Is this normal?

Here is the list of packages to be installed or upgraded

You do generally want the 32-bit libraries with the Nvidia driver, yes. Steam and most games are 32-bit, so they need the 32-bit libraries to work.

If I ever decide to install Steam, I will not mind to install i386 packages.
But, I want to know why all of the sudden update wants to install them?
I have Nvidia driver since I've installed the system, and it didn't needed any 32bit libraries.
Why is Nvidia 450 connected to them? I don't see any other package in this update that would cause this dependency.
