How to buy IBIT living in Switzerland?

I have some money in IBKR and I have tried all possible ways to enable trading there with IBIT, I have read around here that it's impossible.

I also have 5 3a portfolios distributed between VIAC and finpension. I know that finpension allows buy BTC and Etherium ETFs on the 3a, but I don't think that's a good idea. I don't want to risk that money on that.

I am looking for any way to buy IBIT or a similar ETF living in Switzerland, I have checked finpension invest but they don't offer that. Is there any way that you know, either a broker or a robo advisor?
