@TheBobkin Thanks for your insights,
I've checked with Dell where they asked to check with Micron mentioning u.3 will not work in Dell: Latest Firmware for Micron 7500 U.3 NVMe Disk on Dell R750 (16SFF+8NVMe) | DELL Technologies
When checked with Micron, they sent below:
"For any firmware requests that are not listed on the Micron website you will need to reach out and request this through your manufacture rep or distributor directly. We rely on our authorized distributors to handle requests like this and they will be able to assist you further.
If you do not already have a manufacture rep or distributor that you normally work with you can reach out to any listed in the links that I have provided below, and they will be able to assist you further.
Manufacture Rep: https://www.micron.com/sales-support/sales-network/find-a-manufacturer
Authorized Distributors: https://www.micron.com/sales-support/sales-network/authorized-distributors"
Do we have any other option to find this, I am circling back & forth with the three parties.
