Can I travel from Koh Samui to Hua Hin without quarantine after staying in Phuket Sandbox?

Not a Visa specific question, but looking for some advice on inter provincial travel. We are currently in Koh Samui and intend staying here until 6 October. We originally did 14 nights in Phuket (sandbox) early August before travelling to Samui. We are discussing moving on to Hua Hin in October, however, we are unsure if we can do so without having to do any further quarantine ( which we obviously wish to avoid) - the information online is vague/confusing (to me) and any advice would be appreciated- can we travel to Hua Hin without quarantine ?
