Yes you can but you will void any warranty if you do so. First see if there is enough room to pull spring bar ball back and remove one end of spring bar through lever elongated hole. Be aware that you may damage the strap if you force it. Another alternative method is to cut the ball lever off the quick release spring bar with a SHARP pair of small side cutter pliers.
Note: one of the main reasons customers ask us if they can remove quick release spring bars is because they are trying to fit a strap say for example 20mm to a 19mm watch and the quick release does not fit. Check the size of your watch lug and order correct size strap and you will not have any problems with quick release fitting properly.
