How Can I Warehouse, Liquidate, or SPV $2mm in Bytedance RSUs That Don't Fit My Pre-Seed Fund Thesis?

Question about warehousing/liquidating/SPVing Bytedance RSUs a non-thesis holding that doesn't fit my pre-seed fund thesis I have about $2mm in Bytedance RSUs (assuming an implied valuation of $300B). Can't be sold on secondary because of restrictions but they can be transferred via 'forward contracts' that do something similar. I would like to either add to fund or liquidate some of those holdings in Bytedance (about $1m). What are my options? Should I offer this as an SPV on my own? Is there a way to collateralize for a loan the Bytedance RSUs (no bank will do it for these afaik)? Or do I just hold these?
