Like most British TV comedy series, it was recorded with a live studio audience, rather than a "laugh track" added later - so there's probably no versions that exist without it.

There's a chance that it's a 5:1 mix rather than stereo, and might have the audience on a different channel to the main dialogue - which would then be fairly easily to remove in something like Audacity.

Otherwise your options are turning the sound off and reading text subtitles, or using an "llm-powered" vocal remover.
