What are my visa options as a managing director of a Thai company while living abroad?

I co-own a Thai company and I am registered as one of the managing directors.

I used to live in Thailand full-time so it made sense to have the yearly non-B visas and extend them every year at the immigration, but I recently moved abroad and only come to work in Thailand for a max of 3 months a year. We also no longer need the 4 employees and would like to scale down to 1 or 2.

What are my options now visa-wise? Ideally I would like to remain as one of the managing directors.

Thanks in advance!
