Unfortunately for you, No.
The right side of the Safety Lever is formed to the Shaft directly, and I don't recommend trimming off the Right Side Lever, so don't! The Ambi-Safety is also very useful for weak-hand combat shooting drills. Also, ReSale Value will be affected. If you brought it into my Shop for trade or Sale, it would cost you at least 15% value. It's also one of those things that WILL violate your Taurus Lifetime Warranty.
Should you EVER have to use it defensively, such modification WILL be used against you in court, should you be sued by your attackers long lost disturbed cousin, twice removed, that has not seen him in 25 years. (Please note intended Sarcasm) Opposing Council will paint you as a reckless blood-thirsty moron, having tampered with the Safety Devices on your handgun and therefore probably, most likely, accidentally caused the death of the poor innocent dearly departed Axe Murderer/Burglar with a 5 mile long rap sheet. (Please Note more Sarcasm of the current legal system intended)
