Shamsi fell out of favour with South African national selectors before winning a legal battle against CSA that allowed him to play in the ILT20 in the UAE and Australia's Big Bash League instead of the SA20 last month.
"There are no hard feelings between me and the Proteas team," said Shamsi to Rapport.
"Everyone is at ease. It has nothing to do with loyalty or anything of that nature, it is simply a professional opportunity to hone a new skill. I am still 100 percent committed to Proteas cricket for sure."
The 35-year-old is South Africa's all-time leading wicket-taker in T20 Internationals with 89 wickets in 70 matches with his final appearance coming in the 2024 T20 World Cup.
"I did not share any Proteas tactics or talk about Proteas players at all. I am not involved in team or selectors' meetings; I have kept my distance from all that," claimed Shamsi.
"Most teams around the world are neglecting spinners and that needs attention."
The spinner has alluded to stepping away from his consultancy role in order to spend more time at home with his family following his various appearances in global T20I tournaments.
Tom Banton's composed unbeaten half-century and a ferocious Harry Brook cameo steered England to a six-wicket victory over Sri Lanka in a rain-reduced second T20 international, sealing the series 2-0 in Pallekele.
Quinton de Kock praised Ryan Rickleton's ability to adjust to the No 3 role and believes the rest of the lineup will need to show similar levels of adaptability if the Proteas are to win the T20 World Cup in India.
West Indies secured a narrow six-run victory over South Africa in a rain-affected third T20I at Wanderers Stadium on Saturday.
David Miller has been declared fit to join the Proteas squad ahead of their departure to the T20 World Cup after recovering from an abductor muscle injury sustained during the SA20.
