Diodes to turn on/off path for different drive strengths in isolated gate drivers

Question

I am planning on using the ADuM4221 isolated gate driver in my design and I would like to be able to regulate the drive strength. Can diodes be used in the turn on and turn off path to get different drive strengths?

Yes. The standard methods to vary the turn-on and turn-off drive current can be employed on the ADuM4221. 
 Take a look at the theory of operation section in the ADuM4221 datasheet to get more details, the datasheet can be found here
