How to set ad6676's DEC_MODE?

I generated a devicetree and initialized DEC_MODE to 3 on boot time.

I want to change DEC_MODE(decimation) on run-time.

I'm using iio-oscilloscope and I have ad6676 settings gui(attached) but I could not find anything about this issue.

Datasheet describes dec_modes but I could not find anything about how can I change it via libiio or gui.

It only says: 0x140 is dec_mode register. dec_modes are 12, 16, 24, 32...

I tried to change SPI Register 0x140 via iio-oscilloscope but It does not work.

Maybe I need to change some extra registers but I don't know
