By default, you cannot do that. The $80 bit of $FF07 controls this: either you have characters 0-127 and then their inverted counterparts, or all 0-255 characters.
You probably don't need every single character inverted though, so you can probably just use the 256 character mode, and have the inverted characters drawn as they are.
(Or... you could use raster interrupts and such to get around this, but that's not possible from pure BASIC.)
