The answer is almost certainly yes.
Most varnish manufacturers understand that some people have a natural touch with a paint brush, while others need to find a way to spray just about anything. Spraying varnish, regardless if it's a one- or two-part varnish, requires the addition of a proper spray thinner. The proper thinner for spraying allows the material to atomize out of the tip of the sprayer, and level out on the surface, as desired. If you're unsure of your varnish's specified spray thinner, either read the label or contact the manufacturer directly.
The trick is getting the right amount of thinner for the conditions. Each varnish starts with a different viscosity, and depending on atmospheric conditions such as temperature and humidity, each spray nozzle will have different tendencies.
Some varnishes will have very specific spray instructions, but most will give very little detail, because it's hard to predict the type of sprayer, tip, and conditions, as well as the spray technique each customer will have.
