Mixed HDR/SDR manifest fails to play on SDR only device

I have an HLS manifest that mixes HDR and SDR renditions. If I set my Roku to be specifically 1080p, not 1080p + HDR, Roku won’t play any of the renditions and throws a all variants filtered out error. However, if I remove the HDR renditions from the manifest, the remaining SDR renditions play fine. Is there a way to make Roku try the SDR renditions? I found the filterCodecProfiles option on the Content metadata, but that says it is only for DASH streams. And excluding HDR via a bitrate limit won’t work, as there are low bitrate HDR renditions.
