I think you’re referring to the United States Census reclassification of Filipino people from Asian to Pacific Islander? Well, that was a hoax which the Census Bureau responded to here.
In the same way that congress reclassified pizza as a vegetable, you can’t just pass a law and magically change the underlying genetic makeup of an entire ethnic group.
Thats not how this works.

The majority of Filipinos are descended from Austronesians, a distinct genetic group that includes other ethnicities from Southeast Asia, originating between 3,000 and 1,000BC. On 23andMe’s genetic test, this shows up as “East Asian.”
The majority of Polynesians have genetic markers that are much older than Austronesians. We’re talking pre-Holocene era, 12,000BC. On 23andMe’s genetic test, this shows up as “Polynesian.”
Polynesian people moved quickly amongst the islands, so there is not enough genetic variance to determine which island my ancestors are from…but, we know for certain I have no Asian in me.
