It is unlikely that the signature of the bank card will be removed without damage (including scratching/fading/alteration). The bill used by the cardholder to sign on the back of the bank card is called the signature strip, which is one of the anti-counterfeiting measures of the bank card. Generally, it can't be changed after signing, and it will be scratched/faded/altered/damaged if it is changed. It will affect the use of your bank card. If you want to get rid of it, the only way is to break the card and change it.
