HL SIPP - limited to funds, how to benefit from GME?

***EDIT:*** *I'm a true smoothbrain - I just had to sell my current fund to be able to choose GME, otherwise it only gave the option to transfer to another fund.*

I have a small amount in a SIPP held with Hargreaves Lansdown, which I can only invest into funds.

Is there any way of choosing a fund that contains GME or that would benefit from the inevitable rise of GME?
