Okay, so I understand the problem is the A4988 drivers. Instead of modifying and possibly destroying the board, would replacing my current board (Ender 3 v1.1.3) with the new v1.1.4 board solve the Zebra stripes issue? The v1.1.4 board has TMC2208 drivers.
Thanks in advance!!
Edit: after all I think the modification is not that hard. I'll just bridge the resistors with a little solder. I'll try that first.
