That can be accomplished using a combination of EFIS with built-in battery, essential bus architecture, and/or battery backup modules (Like the IBBS).

You haven't mentioned if your RV-10 is for IFR or VFR use.

My suggestion would be to look at a simpler architecture then design in the needed level of backup for your mission.
What if one is using EFI with no mechanical fuel pump?

A single main bus works for most conventional aircraft, both VFR and IFR, with varying levels of backup and redundancy depending on your mission.

If you are running an electrically-dependent engine or some other alternate configuration, the manufacturer of those systems typically specifies the needed electrical system and you should follow that.
