Hi. An cheap option, rake out joints and grind the brick faces. This will allow the render to grip on them.

Plug & screw expanding metal lathing along the bricks or rake out the joints 8-10mm so there’s something for the render to grip on

You can screw wire mesh to the wall before rendering it

I would score the face of the brick with and angle grinder, that way the mortar would be able to grip to the brick better and would be your cheapest option, otherwise tac a mesh to the wall.
