Unlikely.
It's typical Sony locked down walled in product.
It does what it does with PDFs.
If you want to type on PDFs you need
MyWrite Nebo on iOS, or an Android with digitizer / active pen and there are some eink, or MS Surface 3 or later, or other touch screen with active Pen windows.
I nearly bought a Sony DPT once and didn't due to too locked down and walled in and really needing Windows. I use Linux.
