There is no build route for this tier. Unified memory is soldered, so capacity is fixed at purchase. If you want a desktop instead, two GPUs whose VRAM adds up is the alternative; see the Llama 3.3 70B guide.
FAQ
What can a Unified 64 GB system run?
35B MoE models; Llama 3.3 70B at Q4 (tight). Memory figures come from the Ollama library and maker pages; the tier calls are our estimates.
Can I build a Unified 64 GB machine myself?

Do you recommend used GPUs?
