Leveraged ETFs (e.g. TQQQ) in a SIPP?

NotaBene12

I would like to invest in some leveraged ETFs (e.g. TQQQ) in my SIPP

Yes, I know that ETFs like TQQQ are not to be held long-term. My intention is to re-balance a few times per year which adds some protection

However, the problem is that I can't buy US-domiciled ETFs due to MiFID and PRIIP.

Yes, I'm aware that there are some European alternatives to US-domiciled leveraged ETFs like TQQQ but these seem vastly inferior to the US versions (lower liquidity, less protection in case of a dramatic market movement in an adverse direction)

So I want to go for the popular US leveraged ETFs

I remember seeing somewhere that one can effectively trade these in the UK via other means (e.g. futures/options/CFDs).

CFDs seem to be out of question in a SIPP. So I am interested in recipes that involve futures/options.

Can anyone share experience doing this?
