Rock Pi4 and old Sony TV

Hello, is it possible on the Rock Pi 4 to forcefully set the output on the hdmi port rgb limited (16-235) when playing video in LibreELEC? The fact is that I have an old TV (sony kdl32ex402), which has a known problem, when a signal in the YCbCr format is input to the hdmi input, the colors are inverted, the screen may randomly turn pink / green. But when I select the RGB output in the LibreELEC player settings, dark shades become too dark, apparently due to the fact that the rgb full signal is being output. Can this problem be solved?

Better to ask this on libreelec site
