Apart from how you keep water tepid over night.

I've got some Morning Glory Heavenly Blue seeds and the packet says soak
them over night in tepid water.

I've looked on line for advice and some don't mention it, some say
optional, some say "or scratch the seed".

Does anyone have direct experience, perhaps of trying different methods?

They usually come up no matter what you do. They come up a bit faster
with a bit of encouragement. Soaking overnight speeds things up.

They are posh pretty relatives of bindweed. Would probably be a
pernicious weed if it didn't get too cold for them in winter.
