I doubt if overall itching has much to do with having Raynauds. It's common in lupus without Raynauds and a number of other non related diseases, ( thryoid, liver, diabetes, kidney, anemia, some cancers ..) so certainly mention it to your doctor. For me, itching, on the back especially, is a sign of lupus disease activity. When I am in remission I don't itch anywhere.
Sometimes it is due simply to very dry skin so avoid hot water and soaps and scented body care products. Most people wash far more than they really need to. Wetwipes can be very refreshing and cleansing enough.
As Florie says use lotions and creams preferably the specialised ones meant for soothing problems such as excema, rather than fancy beauty care types. Apply when slightly damp. Sarna lotion in the US is helpful and aftersun products with menthol and lidocaine can help but spot test in case of individual allergic reaction and watch out for sensitisation
Aveeno products are excellent.
I have read that epsom salts in bath can help and maybe in compresses too but I am not sure if this is good advice.
One of the problems with itching is that it leads to more itching and thus more scratching. If that is the situation, mind over matter really does work to get over the vicious circle of habit. Applying pressure on individual areas works or tapping and so does keeping cool or careful application of coolth or very cold packs.
Then there are the antihistamines but they are often not much help.
