Can we pass data from DataProvider to BeforeMethod

In my framework, I am getting data from DataProvider but since data has detail about browser detail, I am unable to pass the data to Before Method for WebDriver initialization purpose.

How can we pass data to beforeMethod or other class. My Framework is based on POM design.

-----------------------------Test Class-----------------------------

public class LoginTestSP extends BaseTest {

@Test(dataProvider="getData")
public void test(Hashtable<String,String> data) {
}

----------------------------- Base Test Class-----------------------------

public class BaseTest extends BasePage {

public WebDriver driver;

@BeforeMethod
public void initalize() {
String browser = data.get("Browser");
System.out.println(browser);

}
