HL7800 debug uart console toast after fw

I see in upgrade notes the following

EURY-1979 /
EURY-2084

In past releases, the HL78 was tested and
shipped with the debug console enabled.
This enables some capabilities that that are
not needed in deployed units. A firmware
upgrade to 4.4 will disable the console. It
can still be enabled for debug purposes

Could someone please clarify the steps to do so?
