PIP and maintenance loans

My loan has been approved previously before my personal independence payments evidence was received. My (non-married) partner's income was taken into account leaving me with a lower rate of a maintenance loan.

I'm not able to work at the same time due to disability and was recommended to ask about receiving the full maintenance loan now I am in receipt of PIP. I have received conflicting information on whether this is possible.
Any advice would be much appreciated 👍
