Swamy,
I have located the commentary of Swamy Ramanujar (moolam in Sanskrit) in Namperumal site. The details given in that site at page 25 :

Brahma sutra 3-2-14 அரூபவதேவ ஹி தத் ப்ரதாநத்வாத்
Meaning : அனைத்தையும் நிர்வாகம் செய்வதான ப்ரஹ்மம் ரூபம் அற்றது.
I am unable to post the commentary of Swamy Ramanujar (moolam in Sanskrit) here, since able to select as an image only. My understanding from the English translation is that Brahmam is formless.
adiyen purchased devareer’s upanyasam on Sri Bhasyam in Jul 2021. The audio contained first two chapters and upon enquiry with KKT office, I was informed that upanyasam on chapter 3 and 4 are not performed. Hence, unable to know about the explanation for this sutram.
Request to inform me about Swamy Ramanujar’s view : whether Brahmam is formless or with form?.
