Sure it is. No point in acknowledging that EV fires are little more than an outlier, and ICE engines are statically more likely to catch fire.
Nor is it worth pointing out that no Western nanny state has yet banned EVs due to their dangers.
This is simply some fool exercising what little authority they have.
I'd like to say well-intentioned fool, but this is Thailand and given that EV sales accounted for a fair percentage of vehicles sold in Thailand over the last couple of years, it wouldn't surprise me if some Thai ICE vehicle manufacturing lobby was whispering in a few ears.
it seems to me rather like the controversial vape and the thai tobacco monoply's successful effort to keep them illegal did despite the unhindered sale of cigarettes.
