Around here we have to have an engineer sign off to drill through microlams. Then inspectors will accept engineer ok

You should be able to easily check the allowed holes from the manufacturer, they should have a chart on this. Typically, they almost always allow holes in the middle third of both axes (often even more than that),. But there are likely restrictions on the size and spacing between holes. I'll bet if you just Google "manufacturer + allowed holes" you will bring it up.

Also limitation as to proximity to supported ends.
