Answer 1

i'm not sure your question, maybe can you give a video detail,

<ScrollView
  showsVerticalScrollIndicator={false}
  nestedScrollEnabled // add this
  contentContainerStyle={{ width: "100%", alignItems: "center" }}
>
  <Stack flexWrap={"wrap"} justifyContent="center">
    <SelectBox />
    <FlatList
      mt={"4"}
      showsVerticalScrollIndicator={false}
      data={data}
      nestedScrollEnabled
      style={{height: 300}} // also this
      keyExtractor={(item, index) => index}
      numColumns={2}
      renderItem={(data, index) => {
        return <PortfolioCard />;
      }}
    />
  </Stack>
</ScrollView>

Answer 2

It is not recommended to use Flatlist inside ScrollView . Use ListHeaderComponent instead.

<FlatList
  mt={"4"}
  showsVerticalScrollIndicator={false}
  data={data}
  ListHeaderComponent={<SelectBox />}
  style={{height: 300}}
  keyExtractor={(item, index) => index}
  numColumns={2}
  renderItem={(data, index) => {
    return <PortfolioCard />;
  }}
/>
