It is not the best option, but yes you can use! Just pay attention if the potentials of your working electrode are not changing during your cycles, another thing that you can do is to only put it in your solution during the experiment, and taking it out after every measurement.

I had a discussion with a Ag/AgCl electrode provider before. They mentioned you can use it in alkali solutions but the time should be kept short, several minutes at most. then the electrode should be conditioned in KCl solution again for a long time, minutes to hours.

I would not recommend using Ag/AgCl reference in alkali (I've done this before, and ruined a $50 electrode!) Hg/HgO is definitely the way to go (and they're not that expensive). SCE will also work in alkali, but if you want to use high concentrations of KOH, and you want to be able to compare your results to the rest of the lit, I suggest finding $75, and buying a Hg/HgO electrode (and if most of your experiments will use the same concentration of KOH, you can get one that has the same concentration inside the reference, and not worry about gradients across your membrane)

I have used SCE in 1M NaOH for a period and there was no serious problem. In that time after each CV test  I put RE in Distilled water for recovery and then used it again.

you should be careful about Cl ions release too.

maybe you can try a bridge tube for your reference electrode

In 10 minutes you may imagine and add a salt bridge (KCl 1 M solution). Without a salt bridge the junction of the REF electrode will be clogged in alkaline solution.
