Net NetC304_2 (for IC86's feedback) passes right over LVDS signals
The signals carry the DAC data (up to 500Mbps). The feedback net is low-impedance due to the caps, and it's separated by a ground plane (but only one) and it's at an angle (but not 90°), but since the power supply eventually powers analog electronics it could be optimized. A simple fix is to just relocate the via to the right of C307. A 120p cap can also be added to better filter any high-frequency coupling.
