There are some things you could do with your kayak to make it more likely to stay upright, hut truthfully the main thing is to avoid the waves and rocks (and often, just the waves only) until your skills and gear are up to it. The better your gear, the less skills you need (to a point). The better your skills, the lesser gear you can use (to a point).
Working in waves and rocks is called rock gardening (or rock hopping in the UK) and is a subset of sea kayaking. It takes a lot of the high level skills of sea kayaking and adds in skills from whitewater kayaking. Generally not something for a beginner to do.
Where we move a kayak a little with every paddle stroke, all kayaks can be moved a lot by waves. So along with knowing how to move your boat as best possible, an important part of rock gardening is knowing how to get the wave to move you how you want and how to avoid getting moved by a wave when you don't want.
Very important is also how to get yourself back in to your boat in the conditions you will be in (so with waves washing over you), because rock gardening (like kayak surfing) will involve you getting knocked over reasonably often. The safest recovery from being knocked over is a roll - pretty much considered a requirement for higher level rock gardeners and surfers.
