Yes, but make it nautical — agreement with a salute instead of a shrug.

means An old or dialect way of saying 'yes', still standard in nautical and military commands ('aye aye, captain').

from Origin genuinely uncertain — it appears in English from the late 1500s, and theories link it to 'I' (as in 'I assent') or to Old English/dialect 'yea', but no single root is confirmed. Its survival in naval speech ('aye aye, sir') is what kept it alive long after everyday speech moved on to 'yes'.
