How to make sure QR code is rendered using CMYK?

[moseleyi]

I can't find a configuration or setting to make sure the values for colours are in CMYK not RGB. Is it possible?

This depends entirely on the underlying output module. The EPS output supports CMYK, SVG supports whatever you supply as color value, and for everything else, your best bet is the ImageMagick output, which allows you to specify one of various output formats via the imagickFormat option.

I tried EPS with Imagick but every time I use it it would rasterize it and I need to preserve the vector

Ah I see - it's even in their documentation

IM is a 'raster image processor'

So I'm assuming you want to output EPS - have you tried the QREps output module then? It's not as fancy as the others, but it gets the job done.
