I think that's not possible but you can check with adobe.
But if you want to solve this issue,
You can aem an instance A where you can configure DM Server A and choose another aem instance B where you can configure DM Server B. Now you can use the content transfer tool or through package manager to move the pdf from aem instance a to aem instance B. Once it is done, please run the dam update workflow on instance b .
With this step you can sync DM Server A and DM Server B
