NRF9160 UART Odd Parity

2 extra pin, SCLK and SS and you never mentioned an 'isolation barrier' in your original post either so it was rather unlikely someone replying could take that into account. Anyway you have 2 choices

1) use SPI

2) use a different chip from ADE9153A

oh actually 3 choices

3) use a SPI/TWI/some other protocol to UART chip which supports odd parity on the NRF side of the isolation chip and talk to that and have that talk to the ADE9153A

SPI requires extra pins across the isolation barrier and a much more expensive isolation chip.

You can't. It's even parity or no parity at all. ADE9153A also supports SPI, you could use that instead in your board design, or use a different chip.
