Mount device specific address

Hi, I am working with a GL-AXT1800 and I want to mount an SD card at a specific address (/mnt/sd). The problem is that when I insert the SD card, it automatically mounts at /tmp/mountd/disk1_part1 without any configuration. How can I change the auto-mount address?

Thanks in advance!

Maybe in Luci>System>Mount Points?

I have this config in Mount Points, but the device is mounted in two locations. I do not need the /tmp/mountd/disk1_part1 mount point.
