Prone positioning is not an airway clearance technique. It is used to correct ventilation to perfusion matching which is impaired in acute respiratory distress syndrome (ARDS).

Acute respiratory distress syndrome (ARDS) due to a viral infection (ex. COVID) is not an “airway clearance” problem. It’s a ventilation to perfusion problem due to changes in the epithelial layers of the type 1 alveolar cells and pulmonary capillary.
Normally those epithelial layers create a barrier that only permits at most a trace amount of fluid into the alveoli and the space between the layers. The space between the two layers is incredibly small, it is about 1 cell thick.
