Can I ‘Throttle’ my stop cock?

It's fine to choke your flow down at the mains stopcock. Seen it lots of times.

Usually between half a turn and a full turn from fully closed. You have to experiment to get it "right" for your house and useage.

It's quite amusing, I had to fit a Homeboost pump to get our flow up to 12l/min, the whole street has dire water pressure.

First world problems and all that..

Yes fine, if you overdo it the boiler may not come on and also you may have a whine or whistle caused by the restriction but as long as that is OK no problem.

Many years ago I tried to tame the high pressure on my own supply using the stop cock and it just resulted in annoying hissing whenever a cold tap was opened. Much better to install a pressure reducing valve which gives better control and can help get rid of noises including water hammer.
