you can buy a brand new Bogpod SB-2 bipod with a proper rifle yoke for $29.99...https://www.amazon.com/Bog-Pod-Sportsmans-Shooting-Sticks-All-Terrain/dp/B01F3J3PMC
These are very popular and I see nationally ranked shooters use them very well. I've used one since 2012 without fail. There's no need to buy the more expensive bipods which actually are more fiddly to use.
Without being too picky on the point, the rules specifically exclude tripods (by name). So, you MAY be able to use one for local matches... best to remove the third leg entirely, and check with the MD beforehand.
But I would NOT count on being able to use one at an AAFTA Grand Prix weekend or at Nationals. The pictures you see are of local matches... I've never seen a tripod used at a big match in the shooting position.
Besides, you will have to make a yoke assembly to fit on the camera tripod. More time and material expense than it's worth.
