Both Qobuz and Tidal have this option.
Tidal might be your best option as while MQA has a lot of flaws, it’s really meant for a limited-bandwidth situation like yours. So if you are able to stream at CD-quality and have an MQA DAC or Roon you can listen at, theoretically, a higher-than-CD-quality level.
