Upgrade the soldered ram on radxa 5b

Hi everyone, I wanted to know if it was possible to upgrade the soldered RAM on the Radxa 5b. I currently have the 4 GB version of the radxa 5b and I’ve been looking for information on whether it’s possible to upgrade it to 8/12/16 GB. Based on soldering and experience, I already know someone who can solder similar BGA chips. My question is whether this will actually work. To choose chips compatible with the RK3588, I found this PDF. So far, I’ve found chips available at a decent price, each with 6GB, but that brings the total to 12GB. The chips are MT53E1536M32DDNQ-046: A D8BWF .
