I don’t understand what you are saying.
You are saying you need to eat but will settle for a couple tablespoons of almond milk in coffee. If that’s all you need… you don’t need to eat.
I’m confused on what you are saying.
You can change the hours you fast on the nights you work.
When I did nightshifts I would do this… (assuming a Monday start)
Sunday 7pm - eat dinner & start super long fastMonday 9pm - start workMonday 11pm - open window and eat dinnerTuesday 7am - close window and eat breakfast before bed
Repeat that until Thursday when I would return to normal. It actually helps get a couple of extra long fasts in as after practice I could often skip the Thursday meal altogether through a mixture of having eaten in the morning and being tired
