How to send Safe Area guides to external client monitor

Is there a way to turn on/off Safe Area guides for external monitors? Currently I use the decklink 4k extreme 12G to route out to my grading and client monitors but the safe area guides seem to only be UI-based.
Is there a toggle for this similar to the power windows visibility toggle for the color page? Oddly enough, the safe area guides DO appear on my external feeds when in the color page but not in the edit page but none of the new Cut page overlay features (social media / Broadcast and Film) show in the externals.
