No. .mount units automatically gain dependencies on the devices they are mounted from. Only after all dependencies are fulfilled (i.e. the backing device showed up) the mount is executed, and as first step of that the conditions are checked, i.e. much too late for your case. My recommendation to you: write a generator, see systemd.generator(7) for details. The existing systemd-gpt-auto-generator(8) does pretty much what you want to do already, maybe use that as inspiration. It only supports GPT disk images however, and it auto-detects /var/ partitions only since v245. Generators run very very early at boot and generate units and dependencies. this is where you should genreate your var.mount depending on the partition table. But note you have to implement that very carefuly, and do raw disk accesses, since udev and such is not running that early, nor do you even have the guarantee the kernel itself noticed your extra partition or not yet. The only guarantee you get is that the root partition was already found, everything else might happen concurrently.
