The quick answer is NO.
The deposit bonus is a feature that uses a locked balance. During the deposit bonus, whenever you open a casino game such as slots or live dealer, your locked balance will load automatically and the option to change currency will not be available.
As long as your deposit bonus is available you can only load your locked balance into slots. However if your locked balance drops to 0 and your wager failed, then you do not need to sit and wait for the deposit bonus to expire so you can play with your normal balance.
You are able to cancel the deposit bonus at any, by doing so your locked balance will be deleted no matter how much the amount is, so do that with extreme care, because once canceled this process can not be reversed, and whatever locked balance you had left, it will be lost forever.
