Can i remove hdr from a mkv file and convert dts to ac3 without encoding

[fits79]

Hi.


Is there a way to remove the hdr info of any mkv file so appear like just not has hdr and transform any dts or dts-hd sound into ac3 or truehd sound?


I try mkvtoolnix, tsmuxer e.t.c. but i can't remove the hdr info from the file.
