The basic difference is that while conducting scoping reviews instead of systematic reviews when there is an aim of the drafting review is to recognize the knowledge gaps, simplify concepts or to explore research conduct as compared to scoping reviews that can be used to validate the significance of inclusion criteria, probable questions, identify and map all the available evidences.
# Systematic reviews are a type of review that uses repeatable analytical methods to collect secondary data and analyse it. Systematic reviews are a type of evidence synthesis which formulate research questions that are broad or narrow in scope, and identify and synthesize data that directly relate to the systematic review question.
# Scoping reviews are distinct from systematic reviews in several important ways. A scoping review is an attempt to search for concepts by mapping the language and data which surrounds those concepts and adjusting the search method iteratively to synthesize evidence and assess the scope of an area of inquiry.
They differ in purpose and aims. A scoping review aims at mapping relevant literature on a particular topic of interest while a systematic review is intended to summarize relevant research on a specific question of interest. Both of them have to follow a rigorous and transparent methodology. For more insights, you may refer to the article below.

a scoping review seeks to present an overview of a potentially large and diverse body of literature pertaining to a broad topic, whereas a systematic review attempts to collate empirical evidence from a relatively smaller number of studies pertaining to a focused research question
“Researchers may preference the conduct of a scoping review over a systematic review where the purpose of the review is to identify knowledge gaps, scope a body of literature, clarify concepts, investigate research conduct, or to inform a systematic review.”

I strongly recommend you to read this article by Munn et al., where they debate the differences and define specific indications for each review.
Scoping reviews are a relatively new approach to reviewing the literature, which has increased in popularity in recent years. As the purpose, methodological process, terminology, and reporting of scoping reviews have been highly variable, there is a need for their methodological standardization to maximize the utility and relevance of their findings. Scoping reviews share a number of the same processes as systematic reviews as they both use rigorous and transparent methods to comprehensively identify and analyze all the relevant literature pertaining to a research question.

The specific objectives of a scoping review might be to describe the volume and nature of the existing literature in a topic area, to determine the feasibility of conducting a systematic review for a specific review question within a topic area, or to identify gaps in the body of literature on a topic. Systematic reviews are intended to summarize the literature to address a specific question. Thus, a systematic review can be seen as an approach to compiling the results from multiple studies addressing the same research question.
