Melody Config settings for Digital Mics

We are using 2 Knowles I2S Digital Mics attached to the BC127 HD DISKIT and wanted to know what config options there are for boosting the gain?

We were able to use these commands with Knowles analog Mics but wasn’t sure if these commands worked with the I2S digital…

SET PROFILES=2 0 3 0 2 1 2 1 0 0 1 0
SET HFP_CONFIG=ON ON ON ON OFF
SET AUTOCONN=1
SET DISCOVERABLE=1 0
SET CODEC=3
AUDIO_DIGITAL=0 44100 64 184A90 OFF

( do these commands below effect digital Mics??? )
