No, Qimage uses the Epson driver and can't bypass anything in the driver as the driver supplies the requirements and all software has to obey those. Those (density) settings may not apply or be available if you have color management turned off: if you're using a printer profile in Qimage.
For estimating ink, there may be some third party ink utilities that can estimate ink usage but I believe they estimate how much ink has already been used and they don't "predict". You'd have to Google that because Qimage doesn't do any ink predicting as it has no access to ink delivery amounts: the driver doesn't supply that in any way.
