The CPU does support PTT (platform trust technology) if the system was sold in a market where such technology is not barred by law or US export restrictions.  
Good day, Based on what I read, DELL Inspiron 5570 does not have TPM.... If this is the case, is there any fix for this problem? Can for example download TPN version 1.2 or 2.0. This is of course will help in downloading Windows version 11.  For all the professionals, I need your input how to solve this issue? Thank you for your kind and prompt response.
