MT7612E: how to change radar interference threshold value

I use the openwrt driver, but when test DFS for CE certification, need modify the interference threshold value. So how to change this value？
mt76x02_dfs.c

Start with mt76x02_dfs.c and trace the RADAR_SPEC definitions and uses for etsi_radar_specs. Determine whether the radar interference threshold is exposed anywhere in the driver; done means identifying a supported way to change it or documenting why the value is fixed, with DFS-related tests or validation run if the repository provides them.
