Nope. It is not advisable to substitute EFAs found in the polyunsaturated and monounsaturated fats for saturated fat. Quite possibly the worst advice to be honest.
Saturated fat raises serum Apolipoprotein-B, which is the primary driver of atherosclerosis. Lipidologists are quite clear on this.
"In the last 15 years, several studies have challenged the long-held belief that saturated fats are inherently bad for health. Some studies suggest that saturated fats may not be as harmful as previously thought and can be included as part of a health-promoting diet

. Here are some studies that support this view:
A 2020 Cochrane review found that cutting down on saturated fat intake did not significantly reduce the risk of dying or getting cardiovascular disease
15
.
A 2021 PubMed article discussed the controversies regarding saturated fat intake and cardiovascular health. The article highlighted that results from observational studies demonstrate that dietary patterns with lower average intakes of saturated fats are associated with favorable cardiovascular outcomes, but randomized controlled trials have shown mixed results

.
A 2022 article in the journal "Progress in Cardiovascular Diseases" concluded that more than 20 review papers by independent teams of scientists have found that saturated fats have no effect on major cardiovascular outcomes, including heart attacks, strokes, or cardiovascular mortality, or total mortality

.
A 2014 PubMed article argued that saturated fat can lead to increased LDL cholesterol levels, but the correlative nature of their association does not assign causation. The article also mentioned that numerous meta-analyses and systematic reviews have shown no association between saturated fat intake and cardiovascular disease"
