Not sure I fully understand your logic, but you can insert into xml using sql:variable with curly brackets eg

DECLARE @profiles_xml xml

set @profiles_xml = '
  20
  
    BC4A18CA-AFB5-4268-BDA9-C990DAFE7783
    somename
    
      
         activity1
      
    
  
'


SELECT 'before' s, DATALENGTH(@profiles_xml) dl, @profiles_xml

DECLARE @user_id CHAR(36), @activity_name NVARCHAR(MAX), @display_name NVARCHAR(MAX)
SELECT @user_id = 'BC4A18CA-AFB5-4268-BDA9-C990DAFE7783', @activity_name = 'TEST ACTIVITY NAME', @display_name = 'TEST DISPLAY NAME'

SET @profiles_xml.modify('
    insert {sql:variable("@activity_name")}{sql:variable("@display_name")}
    as first
    into (/Profile/User/Activities)[1]')

SELECT 'after' s, DATALENGTH(@profiles_xml) dl, @profiles_xml
