How to choose RF choke in the biasing circuit of varactor-tuned resonant circuit
Sure you can do a RF choke .Remember that the varicap  diode is running on reverse bias voltage to change the effective Capacitance.This means very low DC current.So you could use a resister instead of the harder to find choke .The resister value should be high enough to not load the tuned circuit .I have used 100Kohm .Your application is different .If in doubt start with 100K. Practical RF chokes have a finite impedance .Getting above 10K is not easy so the resister should work better.
