Question about ASUS ROG Flow X13 RTX 4070

is it possible to change the RAM in this laptop or are they soldered? i know that DDR5 has 2channel per RAM bar is the RAM configured in the single channel or in the dual channel with DDR5 Dan would have to theoretically have 4 channels when X2 modules are installed how is the RAM clocked MHz? Is the GPU 4070 installed internally or in the external GPU dock? According to AMD, a Radeon 780M GPU must be installed internally.
