In the old days, yes. The sensor output gated the write amplifier. There was a jumper block, (usually labeled WP) that could be set to ignore it. (This was back when people like Shugart, Tandon, and Wangco made floppy drives.) These days, the jumper has most likely been taken off for cost reasons, although it might be worth looking for a labled PC board trace that could be cut or jumpered.
