I understood it wrong. You are correct. "RF_SW_CTRL_4, and 5 are for controlling Diversity Switch" -Correct
The TR switch that you have mentioned is internal to the 1PS module and is not really exposed through RF_SW_CNTRL_x pins. Could you please mention why you are looking for this pin information?
As iterated in other threads, Chip down Wi-Fi/Combo design is support intensive and costly from a time to market and regulatory perspective. This is why we primarily support pre-certified partner modules (such as the 1PS) in this space.

What I meant are the controls for T/R at Pin 233(WRF_RFIN_5G) and 239(WRF_PAOUT_5G), are they same as you have replied? From what I know RF_SW_CTRL_4, and 5 are for controlling Diversity Switch. Can you clarify this for me? Thanks!

Is this a very confidential question? the specification is not clear enough , 3rd party supplier is Cypress main customer? if they are doing well I will not asking questions there.

If you are working with a Tier 1 Cypress customer in APAC that is designing either a chip down or module solution, then this should be routed and escalated through our SFDC case system so that the correct internal team can respond. Your local Cypress Sales/FAE team can set this level of factory interaction up for you.
