Add a TXB0101 logic level translator to the LCD_RESET# signal, the VIH(max) if the LCD's reset pin is 1.8V so the voltage needs to be translated from 3.3V logic down to 1.8V logic

The active TXB0101 level translator is used so that the pin can continue to be externally pulled low by a 10k resistor. The behavior of having this pin supplied with a logic level exceed its maximum rating is unpredictable (could be fine but could also act in unexpected ways). The TXB0101 is already used in the design as U1302, so now there will be 2x of these per board. This also requires two additional 0402 X5R 10V 100nF caps (already have 87 per board of CL05A104MP5NNNC / EmCraft PN: E-CAP-003-01, will now be 89 per board).
