Memory requirements for Nordic's ready to use AI models

I understand that Nordic's ready-to-use AI model "Google Speech 35 Commands" needs ~40KB of SRAM and 426KB of NVM.

What I am trying to understand for my project is how much SRAM and NVM is required for non-negotiable firmware for the Bluetooth/Thread stack and so on? 

In other words, how many commands beyond the 35 speech commands noted above could I add before I reach the capacity limit of the nRF54LM20B for example?
