Can ADA4254 be programmed with resistors without digital programming?

Can ADA4254 be programmed as hardware with resistors without digital programming (GPIO parallel OR spi)?
 Datasheet https://www.analog.com/media/en/technical-documentation/data-sheets/ada4254.pdf

You can't get at the gain set nodes from outside the chip. All of its parameters are programed by writing to the internal registers. Why did you think it migh be possible?

It has very low input offset and differential output. 8295 can still be configured as a differential output, but it has a much higher offset. I've never used such an expensive amplifier before or programable .Just wanted to make sure, thanks for your answer.
