The first alternative is to use
without plastering you options are limited to covering it. You could sand down the worst bits, then use something like a polyripple, a textured paint you put on with a roller to disguise it.
Yep, no problem. Just thin it down a bit for the first coat. Fill any screw holes with polyfilla after the first coat, sand down then another couple of coats should do the trick.
Spackling is sometimes mistakenly used as a skim coat. But spackling isn't made for this application – it dries too quickly, doesn't spread smoothly and is hard to sand* to a fine finish on large areas. So, when looking for a smooth, paintable surface, let the spackle do its job: repairing small damage.
Sure, drywall is the gold standard for walls because it's fairly inexpensive, easy to repair, fire-resistant, and more. However, depending on your space's needs, drywall alternatives like plywood, plaster, shiplap, and more can be a better solution.
Without the mist coat you're likely to have very poor adhesion between your paint and your plaster.
You only need to sand old walls before painting. Newly plastered walls should already have an even surface to paint onto, but old walls may have rough spots. The best way to identify the rough areas is to run your fingers over the surface and feel for changing texture.
Please ensure your plaster is thoroughly dry before you consider decorating. The plaster will take a minimum of 3-5 days to dry thoroughly and in some cases longer. Once dry, the plaster will be pale pink and all brown patches will be gone.

This type, like conventional plasterboard, can be finished without plastering over.

Drywall, also known as 'plasterboard', is made of gypsum mixed with water and spread between two large sheets of paper. Plasterboard is used for the construction of interior walls and ceilings. Comparatively, plastering is one of the oldest building techniques.
PVC panels are impact-resistant, whereas drywall is prone to damage. Drywall contributes to landfill waste, decomposing into a pungent-smelling hydrogen sulfide gas. On the other hand, PVC panels are eco-friendly, have a low carbon footprint and can be recycled several times.

Returning your walls to the look and feel of a smooth plaster after years of wear and tear or texturing can seem like a challenge best suited for a professional. But with the right tools, materials, and methods, skim coating can be a cost-effective DIY project to make your interior look like new again.
As a general guideline, you can start by adding small amounts of water, about 1/4 cup at a time, to a gallon of joint compound until you achieve a smooth, workable consistency. You want the joint compound to be about the consistency of yogurt for skim coating.
Use a light-body drywall compound as it's easier to sand smooth.
However, lightweight spackling should be used only for smaller nail-hole repairs and dents, and not for medium-size or large repairs.
However, to put it simply, skimcoat is for more noticeable defects such as honeycombs and waviness on bare concrete. It's also used to give walls a smoother texture if the bare concrete is rough or bumpy. Putty is for minor imperfections such as hairline cracks and slight unevenness on a primed or painted wall.
