You could use the URL constructor and delete the parameter:

const paths = ["/product/Abrasives?gsi=1", "/product/Abrasives?query=search&gsi=1", "/product/Abrasives?query=search&gsi=1&fname=abc"]

function removeParam(path, name) {
  const url = new URL(path, "https://a.com")
  url.searchParams.delete(name)
  return url.pathname + url.search
}

console.log(
  paths.map(p => removeParam(p, "gsi"))
)

Or you could split at ? get the querystring and pathname separately. Use the URLSearchParams constructor and delete the parameter

const paths = ["/product/Abrasives?gsi=1", "/product/Abrasives?query=search&gsi=1", "/product/Abrasives?query=search&gsi=1&fname=abc"]

function removeParam(path, name) {
  const [pathName, queryString] = path.split('?');
  const searchParams = new URLSearchParams(queryString);
  searchParams.delete(name);
  return pathName + searchParams
}

console.log(
  paths.map(p => removeParam(p, "gsi"))
)
