Disable GT Mode and Reverse Mode is this possible?.

i would like to ask if it is possible to disable the fast GT speed mode?, I was out on the board today for only the second time in a month (freedom and excitement), I was travelling down a path on an industrial estate and a lorry came out of a side road quickly. I needed to think quickly and jumped off the board and accidentally pushed GT mode when jumping off. On getting back on I didn’t realise it was in GT mode and i pushed off and the board shifted quickly. I cannot imagine ever needing GT mode and would like to disable it if possible. Is that possible please?. I feel it should be an option.
