I don't think the value of credits can be changed per tenant or customer that easily.
I've actually had a discussion with Microsoft on this subject as they were offering us an EA with a certain license subscription at $X.00 for Y,000 calls per month. When we asked if they couldn't just make the Azure resource that does the exact same thing match that price point in consumption rates in our tenant they said unfortunately no.
I just chalked this up to MSFT sales tactics, but I was told candidly by some others that worked on that Azure resource that they were getting 0 enterprise adoption of it because Microsoft couldn't adjust (specific?) consumption rates to match what they could offer on EA licensing.
Non-profits suffer the same fate where they get credits but have to pay rack rate with no discounts. As a result, running a simple WordPress website uses most of the credits.
