Where do I decrease TX power directly in the driver file so I can recompile?

Hi, I would like to know which file to modify in the driver to decrease the TX power of the 5GHZ band.

I would like to set max 15-20 dBm

I just edited the file rtl8812au-5.6.4.2/hal/rtl8812a/rtl8812a_phycfg.c
setting
int transmit_power_override = 20;

Now it seems the power is quite low; it would be helpful to understand how many dBm that corresponds to.
