I know pretty much all of the cart based ones have a tool and key provider available (or a potential key combo, like the R200/R280/C88), but I don’t know how widespread these 3rd party tools (or leaked copies of the EPSON Adjustment program) are, yet.
Might be safer to manufacture a makeshift lift to remove the pad on these with a metal bar basket and a Dremel, but you want to make sure it’s a little larger than the printer. Find it, remove the screw and only lift it up as needed - no more than that. The problem with these EcoTank machines is that you need to be careful not to spill or cross contaminate the system, which isn’t a problem with the standard models. Hint: If there’s an IEC lead, move to the next possible part. Install the new one and then you have to reset the WIC counter.
All of the 2010+ models are pretty much the same - flip the printer over to find the second biggest part other then the power supply, remove the nearby screw (usually 1) and use a screwdriver to release the pad from the chassis.
