Unhappy Help! Broken N54 Valve Cover Bolt Extraction

My torque wrench failed me and broke off one of the bolts. There is not much head room for me to clamp the bolt out.

The bolt is easily accessible, but I have been trying to use 1/8 drill to drill the bolt, but the lack of precision and moving around makes it very scary (don't want to destroy the engine block).

I've been searching around- mostly found concrete answers for the aluminum bolts on the N52.

Any ideas and suggestions?

Thanks!
