convert raw file to ACEScg exr

[p0las]

Hi,
I'm struggling with this conversion and cannot find any documentation for the parameters that can be passed to libraw. Is there a documentation for that?

my current command is as follows:
oiiotool --iconfig raw:ColorSpace ACES --iconfig raw:HighlightMode 1 -i "0H2A7632.CR2" --colorconvert ACES ACEScg -o "0H2A7632.exr"
but it produces pink highlights. there is a libRaw argument use_camera_wb that might have some impact on this but I don't know what the equivalent one in oiiotool might be. Google is not very helpful and I totally failed to find any documentation for this.
