It is between the pins of the chip in the PCB that the electrical rules are violated. If the safety spacing is reduced to 6mil, the pins of the chip can be displayed normally. In this case,
Yes, your chip pin is already 6mil, so your minimum spacing must be this, but you can also set spacing between different networks. For example, L and N6mil are definitely not acceptable. You can set spacing separately. All PCB software has this function, that is, network-to-network spacing, such as AD(protel) and PADS.
