You can always speak to the VS firm and see if they could change you to a direct TC process instead and explain you now have a TC offer but your preference is to proceed with your application, but you are sure you would need to commit to the TC firm before the VS is complete.You could also ask the VS firm to extend the offer period, but if you are due to start the GDL this summer, then I suspect an extension wouldn’t necessarily help you.
