Can you spray Minwax Polycrylic with an airless sprayer?

Experimentation. You can experiment with spraying Polycrylic, but thinning is not recommended by Minwax. If you try to use a spray gun such as those used for automotive finishes, it may shoot the finish out at too high a velocity, leading to spattering instead of adhesion.

What is similar to Polycrylic?

Acrylic polyurethanes are commonly used in the states. You could also use a laminating resin like West Systems, Resin Research, MGS and so on, but those may or may not be easy to find for you. Standard hobby epoxies won’t work very well. Go the extra mile and just use a vac system and laminating resin.
