P51 (20HH, 20HJ) Latest Thunderbolt 3 Software & Firmware to Support Pre-Boot ACLs

P51 BIOS Update v1.21 & Later advised support for Pre-Boot ACL option on Thunderbolt devices providing the  P51 ThinkPad is running Thunderbolt software version 17.3.73.350 or higher and Thunderbolt firmware NVM 26 or higher (see release notes extract below):

 

*** Extract from n1uuj13.txt release notes ***

[New functions or enhancements]
- Supported Pre-Boot ACL option for Thunderbolt device on pre-boot environment
in ThinkPad Setup - Config - Thunderbolt 3.
(Note)
To use this feature, System need to update
Thunderbolt software to version 17.3.73.350 or higher and
Thunderbolt firmware to NVM 26 or higher.

***

Current Thunderbolt Software / Firmware available for P51 (20HH, 20HJ) from Lenovo support website is 17.1.64.250 / 15. When will latest P51 Thunderbolt software / firmware compatible with above BIOSPre-Boot ACL enhancement become available?

 

I note you have released Thunderbolt software version 17.3.74.400 for P51 (20MM, 20MN) which does satisfy the above BIOS Pre-Boot ACL enhancement requirement, and should be compatible with P51 (20HH, 20HJ) as both use the same Thunderbolt 3 Controller, viz Intel JHL6340 / Device ID 15D9, but this section of support website doesn't include the latest Thunderbolt 3 firmware. When will the latest firmware release be added?
