If you are using the HCI UART port, you must use the flow control which means you must use CTS/RTS.
For watch demo, it uses WICED HCI Protocol. The device will accept the WICED HCI command. You can find the details in doc/WICED-HCI-Control-Protocol.pdf. It is implemented in the application code, you don't need to enter HCI mode.
OK, got it, specification wise hardware flow control is mandated.
But if We try NOT to use hardware handshake, can we get by ?
What we are asking is,
Any one tried practically to use without handshake?
We understand, Cypress will not guarantee the reliable operation without hardware flow control.
But leaving any edge case operations, can we achieve moderate reliability in simple command settings over HCI uart,
No continuous or large data transfer operations expected without hardware handshake.
This will save couple of port pins on host microcontroller.
Any guesswork or idea sharing, without binding commitment.

If you don't want to use flow control, you may use the PUART to communicate and define the command by yourself.
