need bios dump dell latitude 5420 (cpu 11th)

Did you save the original bios before trying others ? .If you did we can check if the service tag in the bios matches with the one you gave, and check if the configuration is ok. If you havn`t got the original bios then we can only assume that the service tag is right one, but the base cover might be from a different laptop.
From the laptop configuration (see attached csv file) based on the service tag the CPU should be an i5-1145g7 - Tiger Lake. You can check the CPU part number to see if it is or not (somettime the motherboard model number will have the chipset name in it).
Also from the configuration you will see it has non-vPro CSME firmware with ME disabled. There are more that 900 posts in this thread and there will be some bios with clean CSME/ME firmware matching that particular configuration.
Use MEAnalyzer to check which bios versions have clean (Configured) firmware or not clean (Initialised) ,and look at the chipset support, if it says TGL it`s Tiger Lake, if it says CML it is Comet Lake. Obviously if you have a Tiger Lake CPU you
don`t want to use a Comet Lake bios.
