With pre-Frame Lock software:
Use Live Video Settings Editor and trial and error in hope of finding magic numbers.
With current software:
If source puts out 23.976 Hz (technically, Blu-ray is not 24.000) and display accepts that, set Frame Lock to Auto in the video processing menu Preamp output frame rate will be identical to source frame rate, overriding menu 8 setting.
Suggestion - set one layer with Frame Lock Off (e.g. DVD1) and another with Frame Lock Auto (e.g. DVD2) all else being equal. Press the DVD button to toggle between the two (you will have to unless you never watch 60 Hz sources). There is no On setting because some sources cannot be locked on to.
Back door in case Frame Lock is turned on and screen becomes blank (i.e. your display does not accept source's rate) - press and hold Mode, when front panel says Scale Output press Mode twice again so Frame Lock is displayed, then press up or down arrow key to change setting from Auto to Off.

Edit: Set menu 8 output to 60 Hz (or 50 Hz if you are in a PAL region) regardless of Frame Lock status
