    It's easy. Find the following in START167.A66:

    ; The following code is necessary to set RAM variables to 0 at start-up
; (RESET) of the C application program.
;

$IF (CLR_MEMORY = 1)
    and modify it:
    ; The following code is necessary to set RAM variables to 0 at start-up
; (RESET) of the C application program.
;

P2 DEFR 0FFC0H
JB P2.0 EndClear

$IF (CLR_MEMORY = 1)
    That will skip the 'clear variables' portion if P2.0 is set. If you'd rather skip variable initialization as well, replace EndClear with EndInit.
