I am trying to update data length extension on BLE on Imx93 board. Using python, i am unable to find any library which support DLE negotiations.

Its IW612 so NXP has a pdf which says, we can do following but I am unable to find how to do it? I am unable to locate their library to do these changes.

bleResult_tGap_UpdateLeDataLength
(
deviceId_t deviceId,
uint16_t txOctets,
uint16_t txTime
);
