Passive losses advantageous for Roth conversion?

[Sateesh Kumar]

Hello

i have a traditional 401k from old employer it has little over 100k, I would like to move it to an SDIRA or Solo 401k to make some alternative investments. I also have some passive losses for this year due to a syndication investment I made this year, can I use this passive loss to my advantage to convert my traditional 401k to a Roth Solo 401k or Roth IRA with minimal to no tax hit? Appreciate your inputs.

Thanks
