Hi,
Lenovo has published ADL 16.1.35.2557 - CORP and CON LP on their x3 Gen8.
Find attached the non-capsule versions 
16.1.35.2557_CORP_CON_LP_noncap.rar (7.9 MB)
Also note from the Lenovo readme:
PLEASE NOTE THAT UPDATING USING NON-CAPSULE METHOD WILL NOT UPDATE THE BACK UP MEFW.
NOT UPDATING BACK UP MEFW INCREASES RISK OF DOWNGRADE OR
SYSTEM NOT BOOTING IF SYSTEM FW GOT CORRUPTED
IF YOU WANT TO UPDATE BACK UP MEFW PLEASE USE CAPSULE METHOD INSTEAD.
There were additional “BU” labeled .bin files also inside the original folder, which I suppose are the same as provided above, so I didn’t include them.
In case you wonder, yes, with Lenovo you can use the capsule update from x3 Gen8 also for models that have a 16.1 Corp LP
CON_18.1.15.2523.bin.zip (3.4 MB)
CSME version: 18.1.15.2523
Extracted from Asus Zenbook 14 UX3405CA bios (Arrow Lake platform).
BTW, The interesting part is you can flash CSME 18.1 Firmware on the system which use CSME 18.0 firmware (Meteor Lake) with no issue.
