How to remove Tx_power(3bytes) in Advertising data packets? ( STM32WB55RG )

Hi I'm mattehw.

When I Tested advertise setting using P-Nucleo-WB55 board, error occurred about advertise max length.

so I have question about STM32WB55 BLE advertise setting.

I want to use Local Name(10bytes) + 128bit UUID(18bytes) in advertising data(max 31bytes) without scan response.

but cant use that because STM32WB55RG basically include Ad flag(3bytes) + Tx power(3bytes) 6bytes in Advertising data packets.

*Local Name(10bytes) + 128bit UUID(18bytes) + Ad flag(3bytes) + Tx power(3bytes) = 34bytes.

so i want to make to disable Tx_power option as below .

*Ad flag(3bytes) + Local Name(10bytes) + 128bit UUID(18bytes) = 31bytes.

As the title says, How to disable Tx_power(3bytes) in Advertising data packets?

Is that a possible?
