RTK resets serial baud rate on start

When connecting up an RTK setup (F9P) the serial baud rate gets auto adjusted. Is there anyway to stop this from happening? We are using another device to deliver the serial connection via a network and the serial port baud rate change means we have to re-configure another device for it to work, which generates unnecessary steps in our setup process.
I guess I’m also not entirely sure of what the check box “M8P/F9P autoconfig” does (on the RTK screen). I’m assuming it does more than just adjust the baud rate, probably also mask angles etc?

Is there away to fix the baudrate and not have it “auto reconfigured”? (i’m aware its possible to fix the baud rate in ublox chip, but the connection process seems to override this).
