Yes, if you want to drop the voltage further, just drop more silicon
diodes in series ...

HUMmmm the Cost of one Resistor
or the Cost of many Diodes . . .
The voltage drop across a diode/diodes is more or less current
independend while the voltage drop across a resistor depends on the
current through that resistor. High volume - big current - big
voltage drop - low supply voltage; low volume - low current -
small voltage drop - high (maybe too high) supply voltage.
