Oh nice, I can help :P
There is a fairly well hidden setting
You can go to Settings > revanced settings (top one) > player > flyout menu > hide audio track
It was greyed out for me, I had to first change Settings > revanced settings (top one) > miscellaneous > spoof video streams > default client > iOS TV
They could also first have both prices and slowly make the “before taxes” less noticeable over years
