Assuming your looking at the board right way up and the upper row, the first pin is = SD switched ground and is needed for detect, the second i believe is DAT0.
Both are necessary for SD functionality
Again, you can steal a couple of the ground pins (check with your meter) and move them over but it’s highly recommended that you replace them at a later date… while some maybe redundent i have no way of knowing for sure what the technical specifications of the connector or SD flex are, while unlikely it’s possible it requires all of them for current handling, regardless, you want them all present for stabilty at the least so consider it temporary.
Practice on a scrap macbook board connector pin or something first, as while this repair isn’t difficult it can be fiddly particularly if you don’t have a microscope…last thing you wanna do is lose another pin or make the connector worse
