Yes, you can. Try

  sudo mount -oro /dev/<your usb drive partition> /mnt

(for a more concrete example, assuming your USB drive comes up as
/dev/sdc and has one partition, say /dev/sdc1):

  sudo mount -oro /dev/sdc1 /mnt

Now if you are using a desktop environment, it will most probably
mount things for you... but read/write.

You can remount it read-only like so

  sudo mount -oro,remount /dev/sdc1 /mnt

Perhaps your desktop environment has some knobs to do that. Here,
I'll have to defer to more DE knowledgeable folks here.

Cheers
