Curious of your statement, as it not being the first time I’ve heard something like this, I looked for more information. This article seems to sum up the factual consensus pretty well.

Afrikaners, the descendants of Dutch settlers in South Africa, codified the nation’s apartheid racial segregation system in 1948 and subsequently subjected the country’s Black population to mass evictions and brutal segregation.

White South Africans, as the end of apartheid neared in the early 1990s, owned the vast majority of the nation’s land. Even decades after the end of the apartheid system, white South Africans still own more than 70 percent of the country’s agricultural land, despite making up less than 10 percent of the overall population. The government’s efforts at land redistribution — including a new January land reform law — are designed to address this disparity.

In his February order, Trump claimed that Afrikaners were “escaping government-sponsored race-based discrimination,” as well as “racially discriminatory property confiscation,” and demanded that U.S. officials draft plans to provide relief, including refugee resettlement, to Afrikaners.

Afrikaners have been vocal supporters of Trump, and Musk, who grew up in South Africa under apartheid, has been a vocal opponent of what he calls “racist ownership laws,” in the country. Musk is not himself Afrikaner but descended from more recent British and Canadian white settlers in the country.

Musk has also been vocal about alleged violence against white South African farmers, claiming in 2023 that “they are actually killing white farmers every day.” The country’s courts have found that such claims are baseless.
