ASRock B550M-HDV: SLIC request

[Allpro1975]

Manufacture: ASRock
Model:B550M-HDV
Bios: 2.3 (AMI Bios)
Links Bios: https://download.asrock.com/BIOS/AM4/B55...30)ROM.zip[url=https://download.asrock.com/BIOS/1155/fatal1ty%20p67%20professional(L3.21A)win.zip][/url]
Bios Flash Tool: Instant Flash
SLIC 2.1 HP for Windows 7 Ultimate

I Have tried to mod this myself, but I've been out of practice I guess. My (old) AMI tool says that it is not an AMI bios, even though AsRock says it is. I've also tried using an older Pheonix/Insyde tool (2.73 from 2017) but It just gives errors about no slic table, or module count mismatch.
Any assistance here would be greatly appreciated.
Thanks in advance!

New Bios just released, 2.4

Any SLIC will do 2.1 and up.

Thanks.
