I'm not being funny but I believe that what you seek is what most people returning to China would want and it's just not possible right now for pretty much anyone irrespective of the country you travel from or your residency/citizenship status.

They've been very effective at sealing off the borders to incoming travellers and strictly controlling who gets in and what happens in the first few weeks once you are in. They have their reasons and whether you believe it's an effective method of controlling imported Covid cases doesn't matter. It's the process now.

At the very least, avoiding quarantine in China is not a realistic goal. It's difficult enough to get entry if you're not a PRC national right now.
