Apple MacBook Pro A2141 16" IC BYPASS

Hi everyone hope all are well

I need a little expert advice on a issue I have and seeing as this forum is full of clever people I thought ask here as you never know.
I recently repaired a logic board 820-01700 which belongs to a 16" 2019 Macbook Pro, however I seem to be missing a component near the T2 Rom chip and is U4730.

The schematics say this chip is (M34128-FCS6_P/T) and it also says there is a bypass for it wondered if anyone come across either the IC or the bypass method.
I suppose it's worth noting googling the part package brings up various replacements most of which point to the iphone 6 anti rollback IC it's the same size but has different numbering on top of it.

Thanks all the best OXY 😁

That's the SEP EEPROM isn't it? Not sure what code that holds and whether it's keyed to the MacBook. Can you get a spares board? Usually the easiest way to get hold of the chip?

Hi thanks for the response, not sure to be honest the schematics give no clue, I have a spare board which was icloud locked changed serial an after the latest Ibridge won't now activate so can use the IC from that.
Hard to say these are paired with board but guess there's only one way to find out thanks again with your help OXY 👍.

kevingill Just to confirm that little IC I replaced from an ICLOUD board and all seems fine so not programmed to work with original board thanks for your help on this mate oxy.😎👍
