Simplification of design - removal of antenna components

Generic Node

I am working on a concept where I use a chip antenna with a STM32WLE5. is it conceivable to use the same board layout as the generic node but minimise on components involved in the antenna circuit? for example could I

1. remove the RF and and analog switches

2. based on the schematics on GitHub, if I assume the switches are in the position shown remove the other circuits that would not be activated in the shown configuration.

This will result in a fixed power selection but the additional components add bulk to the BOM for my purposes in making the leanest node using a chip antenna.

I have marked components that I would remove in red highlighter.
